Get rid of legacy drawing, it's only used for selection,
in which case we can prepare a temporary color buffer and draw
at once. Code is not complete here because we still redundantly
set the draw color in the draw function and don't ommit hidden
faces automatically. Still it works 100% without immediate mode
now.

This patch changes the way we draw meshes by introducing
indexed drawing. This makes it possible to easily
upload and rearrange faces ad lib according to any criteria.
Currently we use material sorting but textured sorting and
hiding will be added to optimize textured drawing and skip
per face testing.
It also adds support for vertex buffers for subsurf
modifiers (Except from GLSL drawing), making drawing of
subsurf much faster without need for bogus modifiers.
Tests show that we gain approximately 20-25% performance
by that for solid mode drawing with up to 50% gains for
material drawing. Textured drawing should also have a
small performance gain, but more substantial optimizations
are possible there.

ImBuf types were getting stored as bitflags in a 32bit integer which had
already run out of space. Solved the problem by separating file type to
an ftype enum, and file specific options to foptions.
Reviewed by Campbell, thanks a lot!
This patch add a new option for transparency meshes : Alpha to coverage, in the game setting panel in material.
The alpha to coverage request a multisample, the best is 8x but 4x and 2x can also give nice render.

This makes sense, since contexts get created at runtime, there is little
reason to require recompilation for this.
Only works on linux currently, will be doing more OSs later
Is pretty much what it says :)
Easy subtitles for everyone!
Supports size, positioning,
a cheap shadow effect (probably will need more work),
and autocentering on x axis.
Now you can go wild with long spanish names
in your soap opera videos.
Will probably be refined as days go by,
but at least it's now ready for testing.
We really don't need to iterate all edges of the mesh every frame to
search for loose edges, this calculation can be cached when filling the
edge index buffer.

Issue here is that intermediate result was clipped as an optimization in
such nodes and thus not converted to the correct type properly. Now only
clip those values if types match.
This keeps both the optimization and the conversion. I looked at
converting uniform types always but it's more involved to compare types
at conversion time for such links because the type was getting
overridden during link duplication.
Most of this patch was created by Daniel Stokes, I'm mostly just cleaning
it up and testing it. Still todo: hardness. I need to figure out how to
handle the integer -> float conversion on a dynamic uniform.

If we fail allocating a proxy texture don't fail, instead create a
smaller nearest filtered image to display in its place.
This can make viewing slow (it's an extra O^3 operation), but this will
probably help us render the tornado in 3D viewport in gooseberry and
still actually see something - despite the rendering taking longer.
I've added a debug print so we can know when this happens.
That was really crappy indeed. Now we have a separate API
for low level OpenGL programs, plus a nice interface for GPU, also
removes some GL calls from main code as a plus :)
The source for the programs is also moved to nice external .glsl files
(not sure which extension convention GPU assemply uses)

Implemented Features
====================
Builtin Stereo Camera
* Convergence Mode
* Interocular Distance
* Convergence Distance
* Pivot Mode
Viewport
* Cameras
* Plane
* Volume
Compositor
* View Switch Node
* Image Node Multi-View OpenEXR support
Sequencer
* Image/Movie Strips 'Use Multiview'
UV/Image Editor
* Option to see Multi-View images in Stereo-3D or its individual images
* Save/Open Multi-View (OpenEXR, Stereo3D, individual views) images
I/O
* Save/Open Multi-View (OpenEXR, Stereo3D, individual views) images
Scene Render Views
* Ability to have an arbitrary number of views in the scene
Missing Bits
============
First rule of Multi-View bug report: If something is not working as it should *when Views is off* this is a severe bug, do mention this in the report.
Second rule is, if something works *when Views is off* but doesn't (or crashes) when *Views is on*, this is a important bug. Do mention this in the report.
Everything else is likely small todos, and may wait until we are sure none of the above is happening.
Apart from that there are those known issues:
* Compositor Image Node poorly working for Multi-View OpenEXR
(this was working prefectly before the 'Use Multi-View' functionality)
* Selecting camera from Multi-View when looking from camera is problematic
* Animation Playback (ctrl+F11) doesn't support stereo formats
* Wrong filepath when trying to play back animated scene
* Viewport Rendering doesn't support Multi-View
* Overscan Rendering
* Fullscreen display modes need to warn the user
* Object copy should be aware of views suffix

ATI driver does not like declaration of gl_FragColor and glFragData in
the same source file (even though only one of the two is ever
referenced), just use one of the two.
and on screen rendering.
Aaaaah, the beauty of driver implementations of OpenGL!
Turns out the problem here is that drivers calculate df/dy differently
in some cases (probably because OpenGL counts y reverse to how the
window system does, so drivers can get confused).
Fixed this for the ATI case based on info we have so far, there's also
the Intel case which will be handled separately (missing info on Intel's
renderer string etc).
Unfortunately we can't really fix this for the general case so we'll
have to haldle cases as they come in our tracker and by adding silly
string comparisons in our GPU initialization module <sigh>.
This patch will fix the color management for the mist and global ambient color.
It will remove the old "Color Management" switch in the BGE "Render > Shading" panel and will use the "Display Device" setting in the "Scene > Color Management" panel instead.
