bx is not really part of bgfx... It's used there, but not everything.
bx vector math is going to get changed in the future, and ideally you should have your own math library.

@OswaldHurlem: are you perhaps using left-handed coordinate system?

I am, but is there any handedness inherit to my example from above? Also, bgfx/bx does not have any documented handedness.

One particular thing that may have led me to believe BX's vector math was left-handed and integral to BGFX was the debug draw example:
It has left-handed coordinates and +Y = Up
