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.

Dumb mistake, forgot the divide.

Probably caused the blending issues.
Buildfix for 32-bit x86, arg.
Inline From/ToRGB(A) to avoid losing SSE.

Otherwise it has to store it, which I'd like to avoid.
Improve SSE usage in software transform.

It's actually already pretty decent (unlike the softgpu), but there were a
few places it could use a bit of help.  Speeds up things with hardware
transform off, or areas that need to use software transform.

Minor perf improvements to software transform
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.
Execute android profiler on Exit.
Workaround for #5652: Force size to 0 if negative.

Should be fairly safe, and passes tests nicely.
