CPPShader

by @relssiegp

A C++ lib to write SIMD code like you would write GLSL: CPPShader https://github.com/gitdepierre/cppshader. I need to clean up the code a bit right now, and I'll add SSE2 support for older CPUs (currently requiring SSE4, but I want to see it working on C2D and Atom. I just need to replace the blendv functions with something compatible with SSE2). Then I'll focus on adding NEON support.
