Some non-trivial tricks had to be done in order to expose the
GL::defaultFramebuffer variable without causing leaks or double frees.
Also, the AbstractFramebuffer has a protected destructor so this needs
another special handling.
The clash of static constructors and members / properties is ...
unfortunate. This is resolved using a minor hack, but I think that's
warranted if it preserves C++/Python API compatibility. The
translation() static constructor and property is not done yet, tho.
Only the double variants (since Python doesn't really differentiate
between 32bit and 64bit floats) and directly into math to mimic Python's
math module.
Only the double ones, exposed as floats, because the extra ALU required
by doubles is negligible to function call overhead. It'll be different
for non-scalar types, but here I use this.
