Added OpenGL acceleration. This is disabled by default, so if it crashes for some people, it won't make the plugin unusable. Turn it on.
It works on my Geforce 9600, and I've also tested on a 6600. Untested on ATI. Runs about 3x faster than in software on my Q9300 (quad-core).
This only supports up to 4 channels: RGB and CMYK should always work, but if you filter a layered CMYK channel, the alpha channel won't be filtered.
Runge-kutta interpolation isn't supported in OpenGL (but I've never noticed a difference anyway). Linear is suppoted and much faster, but that doesn't seem to make much of a difference to me, either.
Added SSE optimizations If you're not using OpenGL, you won't notice much of this, because the stuff that's been optimized is only stuff that's not OpenGL-accelerated.
Thread count selection Selects the number of threads used. The default of "auto" will use one thread for each CPU/core, as usual. Auto-1 will use one less, which can improve responsiveness if you're doing other things while greyc runs. (Lowering scheduling priority doesn't seem to help here, for some reason...)
Pre-blurring This is the same as simply running a gaussian blur before running the filter. This is often an initial step in filtering, so this is included to allow tweaking and comparing this step along with everything else. The default of 0 causes no pre-blurring. The blurring tries to be the same as Photoshop's Gaussian blur.
Reset defaults: Hold ALT and hit "Reset" to load defaults.
Copy to clipboard The "Copy" button copies the current settings to the clipboard, in a form more or less like the greyc commandline. (Settings that don't exist in that version are given fake names.) This can probably be used to paste to other versions, but this is mostly intended for pasting on forums: it's quicker than typing it all by hand, and it gives everyone a standard format to list settings.
Quick save Hold ALT and hit OK (or press alt-enter), and the it'll exit and save settings as if you had hit OK, but not actually process the image. This is useful to modify a recorded action, or to just save where you are, without having to wait for the filter to finish and then undo it. It's also handy when I've set up a filter, but then remember that I wanted to duplicate the layer first...
After this, you can also run the settings you just saved with Last Filter (top item in the Filter menu, or ^F).
Actions cleanup Most people don't change da, dl, etc. They're no longer shown in the action now if they're not changed, so the action view is cleaner.
Split out some settings. The stuff in the "Advanced" box is stuff most people won't need to change.
Zoom is now alt-mousewheel. Changed this to line up with Photoshop's interface.
Turned alt. amplitude on by default. I've yet to see any problems with it, so I turned it on and stuffed it in Advanced.
Adjusted setting names to line up with the command line and GIMP. The commandline names are shown on screen, too (including some fake ones, for reference with Copy).
Maybe increased compatibility with hosts that don't provide gFilterRecord->sSPBasic.
