- Towards a complete fix of VGA console attach/detach: a lot of progress is made but few little things need to be checked/adjusted. - Fix text scroll (at least in text modes) by doing guest-to-guest moves, using the EmulatorCopyMemory function introduced in r68826. - Fix the computation of the screen rows/columns values stored in the BDA, in graphics modes (in addition to the change of r68090), by dividing the graphics resolution by the character heights & widths. Correct values are indeed needed by some programs, eg. QBasic (I also add a CharacterWidth; normally it should be computable using the CRTC registers, and is always == 8 or 9, but still...). svn path=/trunk/; revision=68827
