Merge branch 'alpha_channel_fix'
...
Colors in image.RGBA, image.RGBA64 and generic types with alpha channel should
now resize correctly. There's a small performance hit for these image types even
if they don't use alpha channels though.
Fixes bug #26 .

Merge branch 'NRGBA_support'
...
This adds optimized access to image.NRGBA, image.NRGBA64 types. Internally these
image types are now preferred as they are easier to handle if alpha channels are
used.

Limit spawned goroutines to GOMAXPROCS(0).
...
This change sets the number of spawned goroutines to the GOMAXPROCS
value set by the user.
Using more goroutines than available execution threads is slightly
detrimental to performance (~0.5%), and prevents users of the library
from controlling the number of spawned goroutines.
