Playing around further I've managed to get something kinda working. See
attached image. Left is what I now render via my 3rd party image
library, right is what it is supposed to look like.
Two points to note about the attached image:
1. The colours are obviously wrong.
2. The image seems stretched horizontally. I'm not sure if this
is due to the TFPColor being Word size elements instead of
Byte size elements.

I seem to have answered this myself by simply trying it and casting
TFPMemoryImage to a "friend class" (hack) so I can access the protected
FData field variable.

Afterwards I found the TFPMemoryImage.SetSize() which reallocates memory
based on the image dimensions. So memory usage is not hard-coded as I
first thought.
My earlier questions 3, 4 and 5 I still don't have answers to.
