This change broke the graphics on all three Linux machines I have access
to, with three different video cards and drivers (Intel, ATI, Nvidia).

In ex_bitmap, mysha is vertically too high by about a quarter of the
screen.  This happens consistently any time a bitmap is blitted.
The text in all the examples are garbled.

It does work correctly if I use the vesa driver, so no hardware
acceleration.  Any ideas?
