* Moved preprocessor to Shader and ShaderInclude * Clean up RenderingServer side * Preprocessor is separate from parser now, but it emits tokens with include location hints. * Improved ShaderEditor validation code * Added include file code completion * Added notification for all files affected by a broken include.
