Hi
I've had issues with a console program not clearing the screen when it's
supposed to. I've traced the problem down to dlls/winedos/int10.c function
DOSVM_Int10Handler() with and AH reg of 0x0b.
I've added code for clearing the screen with the specified color, as well as
added a method for doing a total clearscreen to vga.c and vga.h.
It's only tested for textmode and propably won't work for anything else so I
think the fixme should be left for anyone who's up for the task.
A patch is attached, please feel free to comment before i submit to
wine-patches.
Regards
Ulrik
