Hello,

I have bitmaps being generated by a process and need to display them
at ~60Hz.

just a quick note: you don't get to control the refresh rate.

your screen update refresh rate is independent of GTK+. All modern GUI toolkits are driven by the screen refresh rate (aka "vblank"). if your screen refreshes at some other rate, there's nothing the GUI toolkit can do to speed it up.

60Hz is a reasonable common refresh rate, but it's not universal, and you probably should not rely on it being the context in which your program runs.
