Equivalent to gdk_draw_rgb_image that scales output?

["Lewin A.R.W. Edwards" <larwe larwe com>]

Is there an equivalent function to gdk_draw_rgb_image that can do simple 
decimation and expansion, so that (for instance) I can display a 1536x1024 
image at fullscreen size on a 1024x768 display surface?

I have my own decimation routines but they're probably horribly 
inefficient, and also they add an extra read-store for every single pixel, 
because I have to convert my internal full-size buffer to a screen-size 
version at 8:8:8 and then use gdk_draw_rgb_image to get it onto the screen.
