[Mono-winforms-list] GDI+ status: InvalidParameter from LinearGradientBrush

[Stifu]

Sadly, GDI+ and WinForms are simply buggy, especially on Mac.
If you've got an X11 server installed, you could try running your
application this way:

MONO_MWF_MAC_FORCE_X11=1 mono yourapp.exe

This will give better results.
