They aren't much useful in Math namespace and here it allows to handle
also Color3/Color4 types. Moreover all RGBA component names were removed
from Math namespace, so it would be inconsistent to have them there only
in swizzle() functions.
Double has 15-17 significant decimal digits precision, extended
the constant to have 15 decimal digits. On the other hand, float has
only 6-9 digits, so there is no need to have more than 9.
Added just-to-be-sure test for sqrt* constants.
If being careful, it's now possible to swap GlutContext with EglContext.
GlutContext doesn't have keyReleaseEvent() and many keys, but EglContext
doesn't have e.g. mouseMotionEvent().
Query depends on 3.0/EXT_transform_feedback (also PRIMITIVES_GENERATED,
even if it wasn't in the specs), only part of SampleQuery requires
3.0/NV_conditional_render, the rest is in 2.1 already.
They can be used for both floating-point (normalized) and integral
(denormalized) representation and support conversion between them.
HSV conversion is done always using floating-point types.
Getters for RGB(A) were removed from Vector3 and Vector4, they are now
part of Color3 and Color4. Because of this, Framebuffer now accepts
Color instead of Vector.
NumericType is corresponding numeric type with size at least the same as
int. It is used in debug operators for Matrix and Vector to prevent
printing chars as characters.
If the type isn't already floating-point, FloatingPointType is
corresponding larger type with sufficient size for normalization of
given integral type.
Also updated type traits for long types, they are now subclassed either
from int or long long based on sizeof(long).
