GDI: SetDiBits uses hdc with DIB_RGB_COLORS (Notes Client problem)

[Stefan Siebert]

Hello,

I've tracked a bug on the Notes Client. It is related to Lotus Notes 
workspace, which shows the database symbols and their icons.
Up to Wine 0.909 the icons were colored correctly. From 0.910 on the icons 
are black (seems that just the BitBlt mask is shown only).
I found the patch for that behaviour - 'gdi: Better support for 1bpp dib 
sections'.
A deeper look into wine revealed that the hdc parameter on SetDiBits is 
always used to get the color depth.
Before the mentioned patch, parameters to the winex11drv functions for the 
related physDev were set to NULL for DIB_RGB_COLORS.
An easy but not really clean way would be to just create a new hdc for the 
DISPLAY in SetDiBits for DIB_RGB_COLORS and use this instead.

My question is if anyone has an idea how to get this correctly 
implemented.
