[plt-scheme] Re: Status of FrTime

Hi Noel,

Improving the documentation is on my list of to-dos (I assume you have 
looked at the doc.txt file), though I have a lot on my plate for the 
foreseeable future.  If you have questions, I'm more than happy to help, 
and I can probably update the docs on demand.

There may be some things I could do to improve the performance, but if 
you're using a Mac, I'd be inclined to blame most of the problem on that. 
I've run it on fast G4s, including my own Powerbook, and the animations 
are much, much, much slower than on any Intel-based machine I've used 
(with either Linux or Windows).  Surprisingly, the animations are actually 
faster (performance is acceptable) if I run DrScheme remotely on a Linux 
box and send the display to my Mac over X11.  I could do some experiments 
to try and determine if there's anything I can do within FrTime itself, 
but I'm not too hopeful.  Sorry about that.

Also, I haven't updated the version in the PLT repository for quite a 
while, but I (and a student) have been making a lot of significant 
improvements to the language itself, which should be available soon. 
Some of them may improve performance.  We're also working to replace the 
hacky animation library with TexPict.
