Subject: [PATCH] ati-vga: Fix checks in ati_2d_blt() to avoid crash
In some corner cases (that never happen during normal operation but a
malicious guest could program wrong values) pixman functions were
called with parameters that result in a crash. Fix this and add more
checks to disallow such cases.
