fb440c9f82 Need to set hardware viewport params depending on window vs. FBO rendering 
and normal FBO vs. RTT.  Fixes upside down teapot in fbotexture.c demo.
Still need to adjust glDraw/Read/CopyPixels Y direction depending on if
we're doing RTT.

ec1db9db1f In intelReadBuffer() check/update framebuffer completeness. 
Added intel_get_renderbuffer() and intel_get_rb_region() helper functions
to simplify some code (should be inlined in the future).

a7cdbf5c38 Additional login in intel_draw_buffer() to check if any needed renderbuffers 
are software/fallback cases.
The hardware's combined depth/stencil buffer is now treated as such
(ala GL_EXT_packed_depth_stencil).  So the depth/stencil span functions
are effectively merged.  Renderbuffers wrappers will extract the depth or
stencil values when needed.

fe37adfde3 Added _mesa_finish_render_texture() function and reference counting for 
the renderbuffer which wraps textures.

315396ac6c Created new intel_buffers.h file with appropriate prototypes. 
Moved body of intelDrawBuffer() into new intel_draw_buffer() which will do
additional things in future.

ceee2c45cd Fixed bug in intelClearWithBlit(). If clearing multiple cliprects, the 
buffer mask was clobbered after the first rect.
Rename 'flags' to 'mask' to be consistent w/ other clearing code.

b176ef05f2 In intelCopyBuffer(), use renderbuffer regions instead of context's region 
pointers.  Added const qualifiers.  Added comments.

6d6e7a08c7 Fix up intelSwapBuffers: 
- get gl_framebuffer pointer from dPriv.
 - flush current context if bound to window we're swapping.  Previous code
   could try to flush a non-current context.

5df4283b53 FBO Checkpoint: 
Basic FBO hardware rendering now working (fbotest1.c works at least).

6734bab3b2 Checkpoint FBO work: 
The progs/tests/fbotest1.c demo works (yeah!), with some caveats:
 - Only glClear is done in hardware, actually rendering is sw fallback now.
 - Initial expose/draw is broken, works on subsequent draws.
Lots of changes in fallback/span code for FB objects.
Almost full rewrite of intelClearWithBlit() for renderbuffers.
Total rewrite of intelDrawBuffer() function.
Add FBO support to intelClearWithTris() but is currently broken.
Temporary hack in MakeCurrent():
 - since we can't create the screen/static renderbuffer regions in
   intelCreateBuffer() like we should (no current context with which to lock),
   init the renderbuffer's regions in MakeCurrent by copying from
   intel->front/back/depth_region.
Still using old DRI front/back/depth mappings for sw rendering to windows.
When those mappings go away, we'll use the new renderbuffer region mappings.

571bf7a71b Change loops from firstLevel to lastLevel to be inclusive of lastLevel 
(i.e. change < to <=).  Otherwise, 0th image of non-mipmapped textures
wasn't getting mapped and software rendering died.

4ab3b9aa76 Implement glGetTexImage.
