Hi Marco,

There are still a couple of things that should be done before merging.

1) Basic stretching is only in the single band gray, multiband color and 
single band pseudo color rendering routines. The remaining routines need 
to be evaluated for the appropriateness of have stretching capabilities.

2) Transparency band - Transparency should be able to be set from values 
in a band in the current image or from a band in any image loaded.

3) May want/need to add the color ramping to other rendering routines 
(?) <--This dovetails with #1

4) as you mentioned, transparency values should be save in the project file

5) Verification that GUI elements are enabled/disabled appropriately and 
cleanly depending on image type and desired display method

6) testing, testing, testing......

In all it is not that much work, just need two seconds to be able to sit 
down and think about it. Now that I have finished with a plugin that i 
was frantically trying to complete, I will make a concerted effort to 
set aside some dedicated time to wrapping this up.
