  Hello.
  I am writing in C. I have a buffer that I drew on with librasterworks, and now I want to draw any of its subrectangles. This cannot be done with SysFn7. I have only one option: to run a two-dimensional loop over the desired subrectangle and do a SetPixel, but I think that would be bad from a performance point of view. Are there any better ways?
