comment Recommended formats to store bitmaps in memory?
Hans Passant said 32bppPArgb is the fastest format stackoverflow.com/a/13496652/1294758. So is it ARGB or BGRA? I've seen ARGB used a lot. I think I remember a strange layout used in GDI+/.NET which might have been BGRA.

Why is 4-byte indexing faster than 3-byte indexing? Because you can use x << 2 instead of x * 3? Or are there assembly level optimizations also?

Woah! You know a lot but too fast! Can you clarify what "scanline" and "chunky" means?

comment Optimizing hierarchical transform
Excellent! One last question, for hierarchical position, rotation and scale, would I need a 4x3 matrix or a 4x4 matrix?

comment Optimizing hierarchical transform
So when I concat (multiply) 2 4x4 transform matrices (A and B), and then project a vector using that concatenated matrix it will work as if I had first transformed by A then by B?
