How can I tell any drawing routines to use certain rectangular area on display so it is in harmony with Emacs display engine? I thought it was done with faces and inserting characters with certain face; but I am not sure how it was actually done. Are there callbacks I can connect too if I would like to update opengl viewport that I can hook easily into? Where do I look? I am not sure I understand it from image.c; it was there I was looking. I never looked into xwidgets though. Can be just me; but if you can point me to right place to look at I am thankful.
