#include "Magnum/Magnum.h"
Making includes absolute, part 5: absolute includes everywhere. The only places where they aren't absolute are: - when header is included from corresponding source file - when including headers which are not part of final installation (e.g. test-specific configuration, headers from Implementation/)

explicit TextureState(Context& context, std::vector<std::string>& extensions);
De-inline TextureState constructor/destructor. It is heavier than it looks. Also fixed some includes in Implementation subdir.

Follow OpenGL terminology for texture binding units. Until now the textures were bound to layers, which was rather confusing, especially when binding layered textures to layers (gaah). Also the wording might have implied that each texture must be in some layer in order to make it usable in shader. This is no longer the case with (yet unimplemented) bindless texture, so another reason to remove the confusion. All occurences of texture layers were replaced texture binding units to follow OpenGL naming. It was mostly in the docs, except for already-deprecated *Layer enums in shaders, but they will be removed soon anyway.

GLint maxTextureUnits;
Renamed Sampler::maxAnisotropy() to Sampler::maxMaxAnisotropy(). Finally a non-confusing name, hopefully. Sorry it took me too long. The original Sampler::maxAnisotropy() (and also Sampler::maxSupportedAnisotropy()) is now alias to the new one, is marked as deprecated and will be removed in future release.

GLint currentTextureUnit;
Texture-related limit queries. Renamed AbstractTexture::maxSupportedLayerCount() to maxLayers(), which is in fact alias to Shader::maxCombinedTextureImageUnits(). Also renamed Samples::maxSupportedAnisotropy() to maxAnisotropy(). It now has slightly confusing naming, will fix that later. Both original functions are now alias to new ones to retain source compatibility, will be removed in future releases. Also printing the values in magnum-info.
