* Added detection if VBO extension is supported.
* Redraw other 3d views after sculpting.
* Fix brush sometimes punching through mesh with very small polygons,
added an extra epsilon to the ray-triangle intersection.
* Fix#19785: curves not drawing with VBO enabled
* Fix#19553: duplicate Window crashes with VBO's
The convention in Blender was to have GL_VERTEX_ARRAY and GL_NORMAL_ARRAY
enabled by default, and other arrays disabled. The VBO drawing code did
not take this into account. I've made these now disabled by default, since
that makes the code clearer in other places too.
* Multithread parts of multires and subsurf. Only loops working on
face grid data and do no memory allocation have been multithreaded,
others would be more complicated.
* Force some CCGSubsurf functions to be inlined, gives a small overall
speedup in subsurf code.
* Fix sculpting not working correct with transformed objects.
* Fix a few cases of "spikes" on lower level multires levels. There's
still cases where it happens, usually on boundary cornders. The
problem is that in such cases the limit surfaces can be very different
from the low res surface, so the tangent space is very different too..
* Fix crash deleting multires higher levels with level set to 0.
* Fix crashes that happened sometimes when adding faces in editmode.
After testing and feedback, I've decided to slightly modify the way color
management works internally. While the previous method worked well for
rendering, was a smaller transition and had some advantages over this
new method, it was a bit more ambiguous, and was making things difficult
for other areas such as compositing.
This implementation now considers all color data (with only a couple of
exceptions such as brush colors) to be stored in linear RGB color space,
rather than sRGB as previously. This brings it in line with Nuke, which also
operates this way, quite successfully. Color swatches, pickers, color ramp
display are now gamma corrected to display gamma so you can see what
you're doing, but the numbers themselves are considered linear. This
makes understanding blending modes more clear (a 0.5 value on overlay
will not change the result now) as well as making color swatches act more
predictably in the compositor, however bringing over color values from
applications like photoshop or gimp, that operate in a gamma space,
will give identical results.
This commit will convert over existing files saved by earlier 2.5 versions to
work generally the same, though there may be some slight differences with
things like textures. Now that we're set on changing other areas of shading,
this won't be too disruptive overall.
I've made a diagram explaining the pipeline here:

and some docs here:

* PBVH can now be created contain both from face grids or standard
meshes. The former is much quicker to build for high res meshes.
* Moved some drawing code into pbvh (mostly for the frustum test).
* Moved ray intersection code into pbvh.
* GPU buffers also can be built from either mesh or grids now.
* Updated sculpt code to work with this. The ugly part is that there
is now a macro for iterating over vertices, to handle both cases,
and some duplicated code for e.g. undo.
* Smooth brush does not work yet with grids.
GLEW update to version 1.5.1 [11-03-08]
this opens room for Geometry Shader support.
* - Brecht, Campbell told me you did some local changes in order to make it right in Linux. I get to you in order to know what those changes are (or feel free to commit them directly)
* Convert all code to use new functions.
* Branch maintainers may want to skip this commit, and run this
conversion script instead, if they use a lot of math functions
in new code:

I tried to make it integrate more with regular render but couldn't
do it well, it still needs a 3D view to take the settings from, and
can't run in a separate thread due to OpenGL.
However, it is now rendering to an offscreen buffer which then gets
displayed in the image window. This requires FBO's to be available, so
a fallback creating a new window is still needed. Currently available
from the Render menu in the top header.
a system crash and other issues on ATI/Apple, due to a buggy driver
(similar issues reported for other OpenGL applications). For now, work
around it by not using non-power-of-two textures on this combination.
* Fix slowdown/freeze entering editmode on a high poly mesh,
dm->getNumFaces can be slow, don't call it in a loop.
* Fix 64bit pointer casting warnings.
* Enable cache for high res + new preview
* Bugfix for smoke banding (in cooperation with N_T)
Hint: Work-in-progress regarding collision objects so can be broken, didn't test
Hint2: jahka enabled a general particle panel but
* bake button doesn't work
* step is not supported for cloth
* several other things there ;)
* bring back 'player' libtype, after investigation with ideasman.
scons/mingw works nicely, for some reason msvc fails to link still, will look further into it.
* further cleaning of 'player' stuff. Now only 3 libs are remaining, of which ideally the stubs lib will be fixed at some point, fading away into the dark history of not-so-nice code. The current blenderplayer part is still a little bit hackish, I'll see if I can find a better alternative, for now it works good enough.
* first working changes to get blenderplayer linking
* blenderplayer/ moved into source/ (CMakeLists.txt changed for that too)
* added externs for bprogname to gp_ghost, so that it links properly
*enable non-2^n textrues for all gfx cards which support it.
* try to enhance the visual quality under linux a bit when gfx card doesn't support it (still errors visible)
* Converted vertex paint to use the new stroke system. Now supports the same smooth stroke and stroke spacing as sculpt mode.
* Refactored the paint cursor a bit, just sculpt for now but other modes soon.
* A couple warning fixes
* cache for low res (deactivating high res for now)
* new way of view3d rendering of smoke (no longer 3 axes) -using 3dtexture now (introduced into gpu/intern)
* introducing LZO and LZMA libs into extern (makefiles missing for now)
* reducing memory usage after simulating for the frame ended (freeing temporary buffers)
* splitting smoke into 2 modifier for the cache-sake (it cannot handle more than 1 cache on the same modifier-index)
* no color on gui anymore
* fixing non-power-of-2 resolutions (hopefully)
* fixing select-deselect of domain drawing bug
* fixing drawobject.c coding style (making Ton happy) ;-)
HINT #1: If scons doesn't work -> cmakefiles are up-to-date, couldn't test scons (but i tried to mantain them, too)
CODERS HINT #1: we really need a way to disable adding all modifiers through "Add Modifiers" dropdown!
WARNING #1: before applying this commit, deactivate your SMOKE DOMAIN in your old files and save them then. You can open them then savely after that.
WARNING #2: File and cache format of smoke can be changed, this is not final!
* Added Shading and Performance panels in the scene buttons,
containing the options previously in the 2.4x game menu.
* Added show framerate/debug/physics/warnings back in game menu.
* Moved these settings from G.fileflags to scene GameData.
* Enabled Display Lists by default.
* Some other small game scene button tweaks.
