HI Stephane, Toggle between double and float for Matrices is not too intrusive in functionality and performance wise and is something I consider a very bad idea.
Changing between double and float versions of Vec* and associated Vec*Array is very intrusive and well massively impact performance - as OpenGL only handles floats internally so any data you send it will be converted on the CPU.
