Hi!
I have finished documenting glViewport() and glScissor() functions →
http://fedora.pl/~gajownik/nouveau/glViewport_and_Scissor_NV17
Output of glViewport depends on 13 variables (I still haven't figured
out three of them) so it took me some time :/ I've been using this
simple program to test the algorithm →
http://fedora.pl/~gajownik/nouveau/Viewport.c
What do you think about renaming NV10_SET_VIEWPORT_DIMS to NV10_SCISSOR?
If you execute glEnable(GL_SCISSOR_TEST) function,
NV10_SET_VIEWPORT_DIMS changes dimensions of scissor box (not viewport
ones).
I work now on functions from chapter 4 from this ebook →
