* Math: Warning fixes.Tony Wasserka2014-08-251-14/+23

* Pica/Math: Improved the design of the Vec2/Vec3/Vec4 classes and simplified rasterizer code accordingly.Tony Wasserka2014-08-251-81/+115
| | | | | | - Swizzlers now return const objects so that things like "first_vec4.xyz() = some_vec3" now will fail to compile (ideally we should support some vector holding references to make this actually work). - The methods "InsertBeforeX/Y/Z" and "Append" have been replaced by more versions of MakeVec, which now also supports building new vectors from vectors. - Vector library now follows C++ type promotion rules (hence, the result of Vec2<u8> with another Vec2<u8> is now a Vec2<int>).
* Video core: Add utility class for vector operations.Tony Wasserka2014-08-121-0/+578
I wrote most of this for ppsspp, so I hold full copyright over it. In addition to the original release in ppsspp, this provides functionality to easily extend e.g. two-dimensional vectors to three-dimensional vectors.
