[ptx] Release: waveblend 0.1.0 - focus enhancing image fusion tool

[Rik Littlefield]

Sebastian,

Great job!

I ran the same images through the visibility mask algorithm available at 
http://www.janrik.net/ptools/ExtendedFocusPano12/ .  Results are posted 
there -- pretty much the same as yours.

I am not sure how to compare the two approaches.  Both the beaded deer 
and the microscope images seem to be fairly simple cases.  I suppose 
it's time to haul out the macro lenses and try to work a harder 
problem.  (I play with insects in the 1-10X magnification range.  It's 
difficult maintaining fixed nodal point in that range, which makes 
perfect alignment problematic.  I always end up having to edit the 
masks.  But perhaps there are other ways.)
