+3D Rotating Monkey Head
+========================
+
+This example demonstrates using OpenGL to display a rotating monkey head. This
+includes loading a Blender OBJ file, shaders written in OpenGL's Shading
+Language (GLSL), and using scheduled callbacks.
+
+The monkey.obj file is an OBJ file output from the Blender free 3D creation
+software. The file is text, listing vertices and faces and is loaded
+using a class in the file objloader.py. The file simple.glsl is
+a simple vertex and fragment shader written in GLSL.

+Compass example
+===============
+
+This example is a demonstration of Hardware class usage.
+But it has severals drawbacks, like using only the magnetic sensor, and
+extrapolating values to get the orientation. The compass is absolutely not
+accurate.
+
+The right way would be to get the accelerometer + magnetic, and computer
+everything according to the phone orientation. This is not the purpose of this
+example right now.
+
+You can compile it with::
+
+    ./build.py --package org.test.compass --name compass \
+        --private ~/code/kivy/examples/android/compass \
+        --window --version 1.0 debug installd

+Circle Example
+==============
+
+This example exercises circle (ellipse) drawing. You should see sliders at the
+top of the screen with the Kivy logo below it. The sliders control the
+angle start and stop and the height and width scales. There is a button
+to reset the sliders. The logo used for the circle's background image is
+from the kivy/data directory. The entire example is coded in the
+kv language description.

+You can click to add new points to the segment, change the transparency

+animations. The Cap and Joint buttons don't work: SmoothLine has not

+Repeat Texture on Resize
+========================
+
+This examples repeats the letter 'K' (mtexture1.png) 64 times in a window.
+You should see 8 rows and 8 columns of white K letters, along a label
+showing the current size. As you resize the window, it stays an 8x8.
+This example includes a label with a colored background.
+
+Note the image mtexture1.png is a white 'K' on a transparent background, which

+Texture Wrapping and Coordinates Example
+========================================
+
+This example changes texture properties and the properties
+of its containing rectangle. You should see some a multicolored
+texture with sliders to the left and below and buttons at the
+bottom of the screen. The image texture_example_image.png is
+rendered into the rectangle. Sliders change the number of copies of the
+texture (the tex_coords), the size of enclosing rectangle (the taw_height
+and taw_width) while the buttons change how the texture is rendered when more
+than one copy is in the rectangle (the
+texture_wrap).

You can edit the .kv language description in the left pane and see your changes affect the widgets in the right pane.   Your changes will update the widget within a few seconds though the impatient could type 'Ctrl-S' or click 'Render Now'.\n\nYou can explore most Kivy widgets from the menu in the upper left corner.  You can also use this playground to test your Kivy language code and adding a new .kv file to the interface is easy.\n\nSome Kivy widgets are omitted from this catalog or could have more complete .kv representation.

+Kivy Catalog
+============
+
+The Kivy Catalog viewer showcases widgets available in Kivy
+and allows interactive editing of kivy language code to get immediate
+feedback. You should see a two panel screen with a menu spinner button
+(starting with 'Welcome') and other controls across the top.The left pane
+contains kivy (.kv) code, and the right side is that code rendered. You can
+edit the left pane, though changes will be lost when you use the menu
+spinner button. The catalog will show you dozens of .kv examples controlling
+different widgets and layouts.
+
+The catalog's interface is set in the file kivycatalog.kv, while the
+interfaces for each menu option are set in containers_kvs directory. To
+add a new .kv file to the Kivy Catalog, add a .kv file into the container_kvs
+directory and reference that file in the ScreenManager section of
+kivycatalog.kv.
+
+Known bugs include some issue with the drop

+Multistroke Recognition Database Demonstration
+==============================================
+
+This application records gestures and attempts to match them. You should
+see a black drawing surface with some buttons across the bottom. As you
+make a gesture on the drawing surface, the gesture will be added to
+the history and a match will be attempted. If you go to the history tab,
+name the gesture, and add it to the database, then similar gestures in the
+future will be recognized. You can load and save databases of gestures
+in .kg files.
+
+This demonstration code spans many files, with this being the primary file.
+The information pop-up ('No match') comes from the file helpers.py.
+The history pane is managed in the file historymanager.py and described
+in the file historymanager.kv. The database pane and storage is managed in
+the file gesturedatabase.py and the described in the file gesturedatabase.kv.
+The general logic of the sliders and buttons are in the file
+settings.py and described in settings.kv. but the actual settings pane is
+described in the file multistroke.kv and managed from this file.

+Basic Picture Viewer
+====================
+
+This simple image browser demonstrates the scatter widget. You should
+see three framed photographs on a background. You can click and drag
+the photos around, or multi-touch to drop a red dot to scale and rotate the
+photos.
+
+The photos are loaded from the local images directory, while the background
+picture is from the data shipped with kivy in kivy/data/images/background.jpg.
+The file pictures.kv describes the interface and the file shadow32.png is
+the border to make the images look like framed photographs. Finally,
+the file android.txt is used to package the application for use with the
+Kivy Launcher Android application.
+
+For Android devices, you can copy/paste this directory into
+/sdcard/kivy/pictures on your Android device.
+
+The images in the image directory are from the Internet Archive,
+`https://archive.org/details/PublicDomainImages`, and are in the public
+domain.

+describes the interface.
+
+On each keystroke to either shader, declarations are added and the shaders

+Showcase of Kivy Features
+=========================
+
+This showcases many features of Kivy. You should see a
+menu bar across the top with a demonstration area below. The
+first demonstration is the accordion layout. You can see, but not
+edit, the kv language code for any screen by pressing the bug or
+'show source' icon. Scroll through the demonstrations using the
+left and right icons in the top right or selecting from the menu
+bar.
+
+The file showcase.kv describes the main container, while each demonstration
+pane is described in a separate .kv file in the data/screens directory.
+The image data/background.png provides the gradient background while the
+icons in data/icon directory are used in the control bar. The file
+data/faust_github.jpg is used in the Scatter pane. The icons are
+from `http://www.gentleface.com/free_icon_set.html` and licensed as
+Creative Commons - Attribution and Non-commercial Use Only; they
+sell a commercial license.
+
+The file android.txt is used to package the application for use with the
+Kivy Launcher Android application. For Android devices, you can
+copy/paste this directory into /sdcard/kivy/showcase on your Android device.

+Touch Tracer Line Drawing Demonstration
+=======================================
+
+This demonstrates tracking each touch registered to a device. You should
+see a basic background image. When you press and hold the mouse, you
+should see cross-hairs with the coordinates written next to them. As
+you drag, it leaves a trail. Additional information, like pressure,
+will be shown if they are in your device's touch.profile.
+
+.. note::
+
+   A function `calculate_points` handling the points which will be drawn
+   has by default implemented a delay of 5 steps. To get more precise visual
+   results lower the value of the optional keyword argument `steps`.
+
+This program specifies an icon, the file icon.png, in its App subclass.
+It also uses the particle.png file as the source for drawing the trails which
+are white on transparent. The file touchtracer.kv describes the application.
+
+The file android.txt is used to package the application for use with the
+Kivy Launcher Android application. For Android devices, you can
+copy/paste this directory into /sdcard/kivy/touchtracer on your Android device.

+This demo shows how to create and display custom keyboards on screen.
+Note that the new "input_type" property of the TextInput means that this
+is rarely needed. We provide this demo for the sake of completeness.

+Kinect Viewer
+=============
+
+You must have libfreenect installed on your system to make it work.
+
+How it works
+------------
+
+1. The viewer gets the depth value from freenect.
+2. Depths are multiplied by 32 to use the full range of 16 bits.
+3. Depths are uploaded into a "luminance" texture.
+4. We use a shader for mapping the depth to a special color.

+Tree shader
+===========
+
+This example is an experimentation to show how we can use shader for a tree
+subset. Here, we made a ShaderTreeWidget, different than the ShaderWidget
+in the plasma.py example.
+
+The ShaderTree widget create a Frambuffer, render his children on it, and
+render the Framebuffer with a specific Shader.
+With this way, you can apply cool effect on your widgets :)

+Custom shape & collide widget
+=============================
+
+This is a Triangle widget with a triangle shape based on 3 points (p1, p2, p3),
+plus a custom collision function.
+
+The p1, p2, p3 are automatically calculated from the position and the size of
+the Widget bounding box. We are using them to draw the triangle shape.
+(Please note in the kv the special case for Scatter.)
+
+Then we need to setup a new collision function to collide only on the triangle.
+We are using a external method that will check if a point is inside a polygon
+(we consider our triangle as a polygon).

+FBO example
+===========
+
+This is an example of how to use FBO (Frame Buffer Object) to speedup graphics.
+An Fbo is like a texture that you can draw on it.
+
+By default, all the children are added in the canvas of the parent.
+When you are displaying thousand of widget, you'll do thousands of graphics
+instructions each frame.
+The idea is to do this drawing only one time in a Fbo, and then, draw the Fbo
+every frame instead of all children's graphics instructions.
+
+We created a FboFloatLayout that create his canvas, and a Fbo.
+After the Fbo is created, we are adding Color and Rectangle instruction to
+display the texture of the Fbo itself.
+The overload of on_pos/on_size are here to update size of Fbo if needed, and
+adapt the position/size of the rectangle too.
+
+Then, when a child is added or removed, we are redirecting addition/removal of
+graphics instruction to our Fbo. This is why add_widget/remove_widget are
+overloaded too.
+
+.. note::
+
+    This solution can be helpful but not ideal. Multisampling are not available
+    in Framebuffer. We will work to add the support of it if the hardware is
+    capable of, but it could be not the same.
