[ros-kernel] Re: gditest problems

[Jason F. <jas...@ya...>]

My late reply:

Well the first thing wrong with gditest was that line clipping is not
implemented in either win32k.sys or the vga driver. So I altered the
background routine in gditest not to draw offscreen.

The second problem is when creating a compatible DC
(W32kCreateCompatibleDC) which is supposed to, when passed a NULL,
create a DC compatible with the application's current screen. Now
previously I had some really ugly code to do this, which I removed. I
assume that the correct way to get the application's current DC would
be via functionality provided by window stations / desktops. This is
only going to be implemented once the new GDI handles are
implemented.

Rex signed up for this but is probably under a heavy work load at
this time. I've just mailed Rex saying I can try and help with this
task.
