Would it make sense then to keep an internal timer, calibrated with
vga_waitretrace(), and sync draws to that? Lets see, 200,000 hz cpu /
70 hz refresh gives ~2857 cpu cycles between refreshes. Take into
account that the retrace is a fraction of the refresh time, and you
are dealing with somewhere < 2857 cycles, which is fine for something
simple, but wont give you time to blit images. Then again I may be
calculating something wrong...
