1/2 XRender: add a helper function for color conversion [attempt 3]

[Roderick Colenbrander]

Hi,

Add a helper function for converting a gdi color to a XRenderColor.
The previous version assumed 8 bits per pixel and now it should be
generic and should also be able to handle formats like R5G6B5.

Regards,
Roderick Colenbrander
