This is useful for tracking changes in a surface. It takes a surface as a keyword initializer: eg s = SurfaceGL(initialize_with_this = a_surf) Or you can initialize it like a normal surface.

Once the pixel data is changed, either is_dirty will be true, or changed_rects will not be empty. If is_dirty is true: then the whole image needs to be updated. Else: if changed_rects is not empty: update the rects which have been changed.

class SurfaceGL(pygame.old_Surface):

__getattr__ ( self,  name )

__init__ (
        self,
        *args,
        *kwargs,
        )

__setattr__ (
        self,
        name,
        value,
        )

blit ( self,  *args )

fill ( self,  *args )
