Iteration v3.5.0

This image is 640x960 -- insane for a mobile device! Iteration 3.5+ now has PREFERENCES for toggling the nifty intro animations and controlling the ratio between screen resolution and drawing canvas resolution. I originally pushed an update with an unreasonable "400%" scale factor (which means 16x as many pixels) without testing it first. Trying it on my phone caused the app to crash. I suppose there isn't enough memory for the original image, a copy or two of it in various layers of frameworks, and the compressed version all at the same time. Even the bad boy shown here is over half a megabyte compressed (png). If you look at the softer bits on the left lob at full resolution you can see lots of regular texture and banding; that's my integer math at work. I didn't expect anyone to see it actually show up in the images.
