I adjusted setting BESHSRCEND to that from X11 mga_video.c (here matrox_bes.c line
585):
mbes->regs.besHSRCEND = ((source.w - 1) << 16) - cropright;
mbes->regs.besHSRCEND = ((source.x+source.w)-0x00010000 - 1)&0x03fffffc;
With that horizontal scaleing works as expected. But it should be further modified
to take cropright into account.

Vertical scaled crop is still not right. Displayed area is shifted a bit up
(top black bar is smaller than bottom one) and displayed content is shifted up too.
