bool osxGraphicsBuffer::begin_frame ( FrameMode  mode,
Thread *  current_thread 
) [virtual]

This function will be called within the draw thread before beginning rendering for a given frame.

It should do whatever setup is required, and return true if the frame should be rendered, or false if it should be skipped.

Reimplemented from GraphicsOutput.

void osxGraphicsBuffer::close_buffer ( ) [protected, virtual]

Closes the buffer right now.

Called from the window thread.

Reimplemented from GraphicsBuffer.

void osxGraphicsBuffer::end_frame ( FrameMode  mode,
Thread *  current_thread 
) [virtual]

This function will be called within the draw thread after rendering is completed for a given frame.

It should do whatever finalization is required.
