d09b9fa6a1 Math3D: Change the vector swizzlers to return const objects. 
Otherwise, people might be tempted to do things like "some_vec4.xyz() = some_vec3", which compiles fine but does not do the expected thing because xyz() does not return references.

56b83af1f0 Don't use aligned loads in non-inlined funcs. 
I'm wanting things to stay in registers, but that's not realistic for
arguments.  Force inline the others.  May help #5699.

a8a299c2e3 Fix ToRGB/ToRGBA possible accuracy loss. 
It was always like this, but not used as much before.  Shifts are fast and
it eneds to sum anyway, there should not be any benefit to multiplying as
floats, and it will probably lose accuracy.

416df17088 Inline From/ToRGB(A) to avoid losing SSE. 
Otherwise it has to store it, which I'd like to avoid.

6630e45eff Just add a packed version of Vec3f. 
This way we can have it aligned to memory where needed.  I think it'd be
better to avoid this if possible so that we can actually vectorize
spline/etc. code.

Fixes #5673.

473fb866e6 softgpu: Implement vertex preview. 
And move ConvertMatrix4x3To4x4() into a common place since there were
differing implementations, which was only confusing.
