Lee Perry-Smith head.onBeforeCompile is used to bypass three's internal parsing system. The parser is modified to take the default provided chunks or optional user provided chunks, and parses the shader before three's had a chance to (by the time the internal parser sees the template, it's valid GLSL, there's no extra syntax) .
