# Shader Stringification
# We want to use preprocessor include directives to include GLSL and OpenCL
# shader source files in cpp files, but since the sources contain newline
# characters we would need raw string literals from C++11 to do this directly.
# To avoid depending on C++11 we instead use a small tool called "line_quote"
# to generate source files that are suitable for direct inclusion.
