Array efficiency & rendering buffers

[Henrik Eneroth]

Many thanks for the very thorough explanation(s). As usual, D seems to exceed my
expectations. This will be easier than I thought.

On a side note, I realised that using the += operator with a dynamic array
length property didn't work. I guess the (a = a + 1) <=> (a += 1) rationale
doesn't work on arrays (since b.length = b.length + 1 does indeed work, whereas
b.length += 1 does not). Wouldn't that be neat though?

Regards,

Henrik
