problems over matrox fb

[Dmitry Semenov]

Hi
I'm sorry if this is well known problem

I use LibGGI 2.0beta2
I've just tested some ggi drawing function over matrox fb.
I tested 1024x768 F2 with full screen clipping and also partly screen
clipping(something like 10, 0, 1024, 768).
I've found that DrawLine and DrawBox(at least) function have problems when
first (at least) coordinate X is negative.
Sample:
ggiDrawLine(-10, 20, 90, 120);
ggiDrawBox(-10, 20, 100, 100);

line left top end is pointed somewhere
Box disappeared from the screen

I have no problem with X target. I never tested vesafb.


Best regards, Dmitry
