Improved noise using Lumina GLSL noise from
http://lumina.sourceforge.net/ with the authors permission. Added a
2nd shader stack to simply combine procedurals.
Requires the OpenGL-OpenGL package from the PublicContribs repository
to be installed first. It is necessary to manually do "OGLExtManager
initialize" after loading the OpenGL-OpenGL package.
The newest OpenGL package from the Hedgehog repository should also be
merged. Thanks to Andreas Raab for a big performance boost.
This package also depends on a fix for Mantis #6553, which can
temporarily be a trivial do-it-yourself thing. Just change
VectorColor#asVector4 so that it returns a Vector4 instance instead of
a Vector3.
Install the 3 packages, do the 2 manual items above, then in Squeak
open a Tweak Project Window, get a Workspace from the Tools menu,
enter "GPUInfo new chkGLSLSupport" and doIt. If this says that you
have GLSL support, then enter "Wrinkle2 open" and doIt.

It would be really nice if someone could verify that this works on
other platforms and let me know. I have Windows XP and NVidia 5200
FX. It was necessary to include code to change the GLSL source line
endings in order to get the preprocessor statements to work. I am
hoping that I did this properly for all platforms. Thanks!
