How to draw a GdkPixmap with mask onto a drawing area?

[learfox furry ao net]

As the topic states!

I have a GdkPixmap and a GdkBitmap, the pair are a pixmap and mask.
I want to use GDK drawing functions to draw the pixmap onto a GtkDrawing
area but I want to take into account the mask.

Do I need to test the mask each pixel at a time and copy each pixel one by
one? Or is there a more convient way? (without using shaped windows)
