[PD] Smooth motion with GEM

[mathsman at libero.it]

Hi list,

I'm using the patch below on Pd-extended 0.40.3 on a MacBook Pro, MacOsX10.4.11, to test the best setting for the [gemwin] initialization.

Even with a simple 4/3 [rectangle] I can't get smooth motions: if I increase/decrease its dimensions with a [line] (let's say increasing dimensions from 3 to 4 in 10000 milliseconds) the motion is not fluid, it changes by little visible steps. I've tried also to limit the amount of data from the [line] till 40 values per second without significative results.

Any suggestion? Thanks a lot! marco
