It only caused another maintenance burden and was confusing to users.
Now when scene graph is in SceneGraph namespace there is no need for
another grouping. Namespaces are (and should be) sufficient.

Desktop OpenGL and OpenGL ES 2 support can be switched using CMake
TARGET_GLES option. All functionality not supported in ES is marked in
documentation.
If targetting OpenGL ES, GLES2/gl2.h is included instead of GLEW.
Mesh class now uses VAOs only in desktop OpenGL, in ES the buffers are
bound on each draw call.
According to OpenGL specification the sampler uniform takes only texture
layer and not any particular texture. In OpenGL 4.2 it is possible to
explicitly specify desired texture layer in the uniform, so I suppose
it's desired to have shader with fixed texture layers and on the other
hand be able to bind texture to any layer, not only one -- the exact
opposite of how it was in Magnum before.
The shader should now specify in its public API which texture is on
which layer and explicitly set the layer uniforms upon construction. All
setUniform() functions taking textures as argument were thus removed, as
they confuse things a lot.
The textures now have bind() function which takes layer as argument, so
it's now sufficient to only bind the texture before drawing the mesh
without messing with sampler uniform.
While namespaces act for hierarchy, modules are something like "tags" -
usable when you want to check related classes of e.g. CubeMapTexture.
Not sure how to name module for Math and Physics namespaces and
Contexts/Trade, though.
Fixed a few typos in extension names, fixed BPTC texture compression
typos. Removed redundant EXT_framebuffer_object from functions as the
Framebuffer class itself has it.
It's slight copypaste, because operator| doesn't accept typedefs and
extracting the algorithm from Renderbuffer would cause the code to be
overcomplicated and not prepared for more buffer texture/renderbuffer
format additions.
The requirements are cross-referenced to dedicated page, similarly to
TODO and bug lists.
Also updated / improved documentation for some texture / image formats.
