How to draw images with rawfb?

I am trying out Nuklear on a raw frame buffer (boot loader environment - U-Boot).

I can see examples of how to create an nk_image and draw it for openGL, but I cannot figure out how it works with nuklear_rawfb.h

It seems to draw fonts but I am not sure how to make it draw images. Is there an example?

Start by reading nuklear_rawfb.h and compare its image handling with the existing nk_image OpenGL examples mentioned in the issue. Clarify the raw framebuffer image API and the expected U-Boot usage before defining an example; done should be a documented, reproducible way to draw images alongside fonts.
