What are you doing with the RGB565 data? GdkImage only has three
operations really: get from drawable, draw to drawable, and manually
mess with the pixels.

If you want to continue to manually mess with the pixels in RGB565
format, just use g_malloc() to make yourself a pixel buffer and go for
it.

To draw to or from a drawable, the options are probably 1) convert
to/from an 888 format when rendering or 2) write a bit of Xlib code to
use XImage directly.

the best approach probably depends on details of your app and why it's
using RGB565
