FIT_NONE Possible value for setFrameFit(), indicating that the source pixels should be rendered as-is, which may clip them at the frame boundary.
FIT_STRETCH Possible value for setFrameFit(), indicating that the source pixels should be stretched to match the frame dimensions.
FIT_SCALE Possible value for setFrameFit(), indicating that the source pixels should be scaled to fit the frame, and centered inside the frame.
FIT_FILL Possible value for setFrameFit(), indicating that the source pixels should be scaled to fit the frame, centered, and clipped to avoid empty frame space if the source image was bigger than the frame.
