codebase.

"half" class. The build is now 3% faster.

to the Tait-Bryan angles we had for now). Also, change quaternion storage
order to wxyz in order to match the constructors.

and avoid cluttering the compiler's symbol table.

more unit tests for the quaternion to 3×3 matrix conversion.

Euler angles to a rotation matrix. Also fix quat::rotate() which was not
building the correct quaternion.

that WinDef.h insists on shoving down our throats.

mathematical writing, and add static constructors to create quaternions
from a rotation.

code for all matrices.

of compiler warnings in 64-bit mode when sizeof(foo) is used as the
argument for the array subscript operator. No need to care about the
non-signedness since only positive indices work.

time, for now the .h takes 17 seconds to compile for each file!

that are not explicitly real, even with namespace mistakes.
