Module "project"

Transforms given point p (4D, homogeneous coordinates) with 4x4 matrix mvp, applies perspective divide and then transforms XY components with 2x3 matrix view matrix. Returns 3D vector. The result Z component can be used for depth sorting.

Same as project, but slightly faster and more convenient for the most common use case of projecting a 3D input point (assumes w=1 for its homogeneous coordinate, i.e. [x,y,z,1]). Returns undefined if the computed perspective divisor is zero (and would cause in NaN results).

Reverse operation of project3. If invert is true (default: false), both mvp and view matrices will be inverted first (non-destructively), else they're both assumed to be inverted already.
