You don't start with the small questions, do you... ;-)

Mainly, look at existing code for features that do something similar to 
what you want, and imitate what you see.

That would be a lot easier.

Hmm...POV uses the position of the pattern ID in PATTERN_IDS (in 
pattern.h) to tell block patterns from other patterns, so make sure you 
put it with the "ordinary" patterns. The blend map stuff is handled 
automatically. If you had it working right as a block pattern, you 
probably added some code to the blend map parsing code that you need to 
remove now...block patterns are actually more complex then float 
patterns.
