示例1: AddFrame
/** Add an animation frame
*
* @param tr A Rect object containing the texture coordinates for another animation frame
*
* Operation:
* -# Retrieve a pointer to the texture for this overlay
* -# Find it's dimensions
* -# Precalculate a scale value to convert 0->max to 0->1 so you can specify the rectangle in pixels, but convert them into texture coordinates
* -# Convert the rectangle passed into the method into texture coordinates
* -# Invert the y coordinates of the texture coordinates (rectangles are specified where
* the origin is the top left, but texture coordinates specify the origin as the bottom left (hence why the y must be inverted)
* -# Stores the texture coordinates generated, sets the default animation frame to be the first frame
