Squeak4.4 base image, where the current development process is going on.
Anyway, Tweak is a huge step forward in GUI building, with it's simplicity,
clarity and Croquet ready functionality. And these days I have tried to
load TweakCore and TweakExtras on Squeak 4.4, and with some modifications
it's seems to be working! So, alongside with CroquetGL package your
project, just should be run on current Squeak. I'll try to do it, and share
the results.

By WebGL shader's generator, being running on Smalltalk side, I mean "webgl
streaming" from Squeak to Web browser, like what is done in Blender 3D
community (https://www.youtube.com/watch?v=UDIn8T4H7xE). So, for doing that
we have Andreas's WebServer with websocket support and CroquetGL on the
Squeak side, and ThreeJS (or GLGE) on the client side, hosted at the same
WebServer or Seaside app. More over, it will be better to stream just onto
the novel Virtual World Framework, Croquet compatible.
