void glxGraphicsWindow::begin_flip | ( | ) | [virtual] |
This function will be called within the draw thread after end_frame() has been called on all windows, to initiate the exchange of the front and back buffers.
This should instruct the window to prepare for the flip at the next video sync, but it should not wait.
We have the two separate functions, begin_flip() and end_flip(), to make it easier to flip all of the windows at the same time.

bool glxGraphicsWindow::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.
