Vladimír Vondruš	515637c76a	Math: implement a robust and faster Matrix4::normalMatrix(). This change makes the operations split into a bunch of separate functions, making the parts easier to document, however with a slight negative effect on debug performance: Starting Magnum::Math::Test::MatrixBenchmark with 16 test cases...

Vladimír Vondruš	e3a820f468	Math: benchmark basic Matrix operations. So I'm sure the next additions don't make things worse -- in the debug build, in particular.

Vladimír Vondruš	13b4bf8461	Math: use __builtin_sincos for sincos() on GCC. Makes this thing faster on Debug. But I'm not sure whether it's due to less function calls or this intrinsic being actually faster, heh. Probably a combination of both.	7 years ago

Vladimír Vondruš	75ffd39fe0	Math: make it possible to use Deg/Rad in all functions. This should have been here ages ago, haha.	7 years ago

Vladimír Vondruš	442d5576d0	Math: change the way BoolVector is printed to Debug. Found while working on the Python bindings --- BoolVector4(0b1010) got printed as BoolVector(0101), which is totally confusing. Now it prints it in a way that looks exactly the same as when constructing the vector with binary literals.	7 years ago
