MX (Multiple conteXt) support was dropped from the GLEW 2.0 library to make core profile support cleaner.
Our WITH_GLEW_MX build option was OFF by default already; this commit removes the inactive code paths.
I'm working on a plan for multiple GPUs, contexts, resource sharing, etc. This commit gives us a cleaner starting point for that upcoming work.
Tested on Mac, will test on Linux & Windows immediately after pushing.
Those tokens are still valid. Although we should not being using them,
they should not prevent us from building with core profile.
In the future we can have a new flag WITH_GL_CORE_STRICT for those.
But only after we build with core profile by default
First: we settle on core profile 3.3, not 4.1. Second, GL_CURRENT_PROGRAM still exists in 4.1 and 4.2. But it is recommented to use GL_ACTIVE_PROGRAM instead.
Following the logic of gl-deprecated.h we should define it to USE_GL_ACTIVE_PROGRAM instead. That said, removing it for now.
This is an auto-generated list, crossing gl-deprecated.h, glew.h and the
Blender code. It allows Blender to build with core profile.
WITH_OPENGL_LEGACY=ON: nothing changes
WITH_OPENGL_LEGACY=OFF and WITH_GL_PROFILE_CORE=OFF:
It stubs deprecated legacy calls.
WITH_OPENGL_LEGACY=OFF and WITH_GL_PROFILE_CORE=ON:
It stubs deprecated legacy calls thus allowing Blender to build with
core profile only.
Technically you only want to use WITH_OPENGL_LEGACY=OFF when
WITH_GL_PROFILE_CORE=ON. But it doesn't hurt to have it working for both
scenarios.

While SCons building system was serving us really good for ages it's no longer
having much attention by the developers and started to become quite a difficult
task to maintain.
What's even worse -- there started to be quite serious divergence between SCons
and CMake which was only accumulating over the releases now. The fact that none
of the active developers are really using SCons and that our main studio is also
using CMake spotting bugs in the SCons builds became quite a difficult task and
we aren't always spotting them in time.
Meanwhile CMake became really mature building system which is available on every
platform we support and arguably it's also easier and more robust to use.
This commit includes:
- Removal of actual SCons building system
- Removal of SCons git submodule
- Removal of documentation which is stored in the sources and covers SCons
- Tweaks to the buildbot master to stop using SCons submodule
(this change requires deploying to the server)
- Tweaks to the install dependencies script to skip installing or mentioning
SCons building system
- Tweaks to various helper scripts to avoid mention of SCons folders/files
as well

The issue was caused by the following construction:
def = env['SOMETHING']
defs.append('SOMETHING_MORE')
Since first assignment was actually referencing environment option it was totally
polluted hawing weird and wonderful side effects on all other areas of Blender.
Ghost depends on glew-mx, so glew-mx should be passed to linker after the ghost.
We're also using spaces for indentation in python, including scons rules.
