It prevents unwanted implicit conversions from e.g. nullptr to Camera,
Vector2 to Physics::Point etc. By making all the constructors explicit
it is easier to routinely add the keyword to all new classes instead of
thinking about cases when to add and when not to.
Buffered* hinted that it has something to do with caching, streaming or
whatever. "Buffer texture" is now also consistent with naming in
specification.
Magnum.h now doesn't include anything except OpenGL headers, thus
changes in Math library don't trigger recompilation of everything, but
only of things really depending on it.
Math constants moved to separate file for similar reasons, de-inlined
some functions to remove the need for some #includes.
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.
This reverts commit 79945ab6fc.

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.
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.
For classes which already have pure virtual functions instantiation is
not allowed, but for other there needs to be at least one pure virtual
method: the destructor.
Pure virtual functions actually can have implementations, but they must
be called explicitly. Destructors are called explicitly, so for them it
works.
The requirements are cross-referenced to dedicated page, similarly to
TODO and bug lists.
Also updated / improved documentation for some texture / image formats.
* Framebuffer related functions moved to Framebuffer class, thus
simplifying the data setting functions - removed setDimensions(),
more flexible setData() function.
* Allow to set data with explicit format specification, reorganized
function parameters to make these two setData() more similar.
* Now using new AbstractType::ComponentType enum instead of basic Type,
updated TypeTraits to return the new enum from imageType() function.
