Disabling display lists for legacy ATI cards since they don't support display lists well.
Also removing an unused variable from the display list rasterizer.
window, the game would stop drawing in the first and mess up the OpenGL state of
the second.
Also fixes glPushAttrib/glPopAttrib getting out of sync in some cases.
brushes, due to issues with color coded drawing or slow/buggy reading from such
a buffer on some systems.
In case multisample is enabled now, it uses an offscreen buffer for such drawing,
which is not multisampled and so should not cause issues. This does mean there is
some extra GPU memory usage when multisample is enabled, and we could optimize
triple buffer to work together here somehow to share buffers, but it's better than
having selection not working.
* Rename functions and move to own header.
* Add wrapper functions for glLight.
* Auto detect if we can use faster code for solid lighting.
* Various fixes for textured draw mode.
code is still unused, but the intention is to use this to solve the double sided
lighting problem on NVidia, and to make the materials work on OpenGL ES 2.0
eventually.
The code works and matches the fixed function lighting pretty much exactly, but
still needs optimizations. The actual integration in object draw will be
committed later when more fixing & testing, there's lots of different combinations
and unclear OpenGL state here.

Implementation notes:
- Matcaps are an extension of Solid draw mode, and don't show in other drawmodes.
(It's mostly intended to aid modeling/sculpt)
- By design, Matcaps are a UI feature, and only stored locally for the UI itself, and
won't affect rendering or materials.
- Currently a set of 16 (GPL licensed) Matcaps have been compiled into Blender.
It doesn't take memory or cpu time, until you use it.
- Brush Icons and Matcaps use same code now, and only get generated/allocated on
actually using it (instead of on startup).
- The current set might get new or different images still, based on user feedback.
- Matcap images are 512x512 pixels, so each image takes 1 Mb memory. Unused matcaps get
freed immediately. The Matcap icon previews (128x128 pixels) stay in memory.
- Loading own matcap image files will be added later. That needs design and code work
to get it stable and memory-friendly.
- The GLSL code uses the ID PreviewImage for matcaps. I tested it using the existing
Material previews, which has its limits... especially for textured previews the
normal-mapped matcap won't look good.
When FBO failed in a particular way it could cause the opengl draw buffer to be
set wrong, effectively disabling all opengl drawing. The FBO error was caused
by cycles GLSL materials with no nodes that would still use blender internal
materials, which caused issues with lamp shadow buffers FBO.
This also fixes a GLSL refresh issue when switching render engines.
not do correct partial updates, now it remembers if the opengl texture is a
non-color data texture or not and takes that into account for the update.
Also includes some renaming ncd => is_data for consistency with color space
terminology used elsewhere.

* Shadow color now usable in the BGE
* Simplified the shadow panel while "Blender Game" renderer is active
* Added variance shadow maps for the BGE
* Buffered shadows on sun lamps in the BGE (orthographic)
* Light textures in the BGE

This makes debug output easier to read - event debug prints would flood output too much before.
For convenience:
--debug-all turns all debug flags on (works as --debug did before).
also removed some redundant whitespace in debug prints and prefix some prints with __func__ to give some context.
- spelling - turns out we had tessellation spelt wrong all over.
- use \directive for doxy (not @directive)
- remove BLI_sparsemap.h - was from bmesh merge IIRC but entire file commented and not used.
Disabled double-side lighting by default and changed areas which are using
double sided lighting to switch it off just after doing stuff which requires
double side.
This makes code a bit more simple to follow (no all that disabling double side
lighting all over the code and so).
This change also fixes crash of blender caused by intel gme965 driver which
leads to stack corruption in some place when double side lighting isn't
disabled (probably driver still kind of using double side in some areas or so).
Hopefully it'll also fix#30293: Converting Text to Mesh
Thanks to Campbell to assist writing this patch!
support in some older cards, now it does a more precise check for problematic
cards so that it can be enabled on new cards that do support it properly.
- use more logical names for strings, noticed too many strings called `str` when reviewing name patch.
- pass __func__ macro to uiBeginBlock(), quite a few names were wrong (copy/paste error).
