Detailed Description
A QPaintedTextureImage provides a way to specify a texture image (and thus an OpenGL texture) through a QPainter. The width and height of the texture image can be specified through the width and height or size properties.
A QPaintedTextureImage must be subclassed and the virtual paint() function implemented. Each time update() is called on the QPaintedTextureImage, the paint() function is invoked and the resulting image is uploaded.
The QPaintedTextureImage must be attached to some QAbstractTexture.
