Hydra considerations

While experimenting with the AIF toolkit i noticed some glitches that could be taken into consideration by the AIF team before going final with the release:

• it seems that image-type function parameters are bound to the selected images according to their alphabetical order, instead of the natural user-defined one: for instance, create a new kernel as here, select two images and refresh; you should be now looking at the image you loaded via “Load Image 2…”: now rename “in image4 srca” to be “in image4 srcc” and refresh. Wrongly, you are now looking at the first image
• the GUI doesn’t release cpu/gpu resources while minimized in order to relieve the machine from the rendering process

Aside that, i’m looking forward to try all this cool stuff with Astro!
