Hi bearophile,
Thanks for the reply. I changed it to 0..height and it has no
measurable effect to the runtime.
The reason I used iota(height) was to test
std.parallelism.parallel. On Windows if I do foreach (y;
parallel(iota(height))) I do get almost 4x speed up on a quadcore
computer. However, on OSX, parallel() either does nothing (LDC)
or makes it slower than single threaded(DMD).

Don't do this:

Use this, because those abstractions are not for free:
foreach (y; 0 .. height)
