### GLPaint ###================================================================================DESCRIPTION:The GLPaint sample application demonstrates how to support single-finger painting using OpenGL ES. This sample also shows how to detect a "shake" motion of the device using the UIAccelerometer class.By looking at the code you'll see how to set up an OpenGL ES view and use it for rendering painting strokes. The application creates a brush texture from an image by first drawing the image into a Core Graphics bitmap context. It then uses the bitmap data for the texture. The image used for a texture must have dimensions that are a power of 2. To use this sample, open it in Xcode and click Build and Go. After the application paints "Shake Me", shake the device to erase the words. Touch  a color to choose it. Paint by dragging a finger.NOTE: If you run the device in the simulator, you won't be able to erase. You will, however, be able to paint.================================================================================BUILD REQUIREMENTS:Mac OS X v10.5.3, Xcode 3.1, iPhone OS 2.0================================================================================RUNTIME REQUIREMENTS:Mac OS X v10.5.3, iPhone OS 2.0================================================================================PACKAGING LIST:AppController.hAppController.mUIApplication's delegate class i.e. the central controller of the application.PaintingView.hPaintingView.mThe class responsible for the finger painting.SoundEffect.hSoundEffect.mA simple Objective-C wrapper around Audio Services functions that allow the loading and playing of sound files.EAGLView.hEAGLView.mConvenience class that wraps the CAEAGLLayer from CoreAnimation into a UIView subclass.main.mThe main entry point for the GLPaint application.Recording.dataContains the path used to display "Shake Me" after the application launches.Particle.pngThe texture used for the paint brush.================================================================================CHANGES FROM PREVIOUS VERSIONS:Version 1.6Updated for and tested with iPhone OS 2.0.
