[nouveau] glViewport()

[Dawid G. <gaj...@fe...>]

Hi!

	I have finished documenting glViewport() and glScissor() functions =E2=86=
=92=20
http://fedora.pl/~gajownik/nouveau/glViewport_and_Scissor_NV17
Output of glViewport depends on 13 variables (I still haven't figured=20
out three of them) so it took me some time :/ I've been using this=20
simple program to test the algorithm =E2=86=92=20
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,=20
NV10_SET_VIEWPORT_DIMS changes dimensions of scissor box (not viewport=20
ones).

I work now on functions from chapter 4 from this ebook =E2=86=92=20
