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.
Long-standing TODO. It is better to have size first, because it is more
significant than type (e.g. because there are Vector4<T> specializations
and not VectorT<4> specializations). It is also IMHO easier for user to
distinguish/read the type than before:
Vector<float, 4> -> Vector4<float> // before
Vector<4, float> -> Vector4<float> // now
* 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.
Checking whether given type can be used for mesh indices or image data
was always done like this, because it was also needed to get OpenGL type
ID for the type:
TypeTraits<typename TypeTraits<T>::IndexType>::glType()
This was cumbersome, now the check is done using function, which
returns the OpenGL type ID directly:
TypeTraits<T>::indexType()
Also replaced TextureType with imageType() and renamed glType() to just
type().
Fuzzy comparison is implemented only on floating-point types with
type-specific epsilon, on integral types classic operator== is used.
TypeTraits class is now extension of Math::TypeTraits (where it makes
sense).
