That sounds interesting where will it endup? In which mercurial repo?

What we do is generate shaders for OpenGL and D3D from this language. We also generate Java code and SSE native code. For some shaders, we ended up generating them and then hand-tweaking them from there.

There is an "ME" based backend for JavaME which I don't think is even being used anymore, so there is stuff here we could remove to reduce the size of the project (and I will be filing a JIRA for this).
> decora-compiler isn't really that interesting in isolation, although at one time we had entertained the idea of popularizing it so that people could write their own shaders with JSL (the decora shader language), in which case the compiler would be part of the JDK such that you could create your own effects. Decora is predominantly used for the "effects" -- blur, box blur, etc. Although it is also used for prism shaders, we don't generate SSE or Java backends for those, and many of these have been tweaked by hand vs. simply generated.
