// Self-contained Wavefront OBJ viewer for Windows and Linux
// (or anything that has SDL2), using softrender. Fairly limited:
// no materials/textures, no points/lines/curves/NURBS, no
// smoothing groups. Not fast, but should be usable up to
// about 500k triangles.
// Usage: viewobj [--fullscreen] [--size=WIDTHxHEIGHT] FILE

    In-place (de)interleave array of size 2*n, in O(n) time and O(1) extra space.

    The "interleave" operation on an array produces an array of
    alternating elements from its lower and higher halves:
        a[0],...,a[2*n-1] -> a[0],a[n],a[1],a[n+1],...,a[n-1],a[2*n-1]
