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.
Now whole Magnum, Magnum::SceneGraph and Magnum::Math namespaces are
fully documented -- each class has at least "getting started"
documentation, larger modules are documented on separate pages.
Now the #version string is added from Shader class itself, making it
possible to do workarounds for older versions more conveniently. As a
consequence, #version must not be part of shader source anymore.
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.

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.
The class is now created always on the stack, so the user doesn't have
to delete it explicitly. It's now possible to write less verbose
shader code, instead of three lines before:
Shader* s = Shader::fromFile(Shader::Fragment, "Shader.frag");
attachShader(s);
// ...
delete s;
It's now only one:
attachShader(Shader::fromFile(Shader::Fragment, "Shader.frag"));
The requirements are cross-referenced to dedicated page, similarly to
TODO and bug lists.
Also updated / improved documentation for some texture / image formats.
Not using macro this time, as some classes could want only to disable
either copy or move and with macros this would become unintuitive and
error-prone.
