Global variables which can be calculated in C++ code are now written as
constant values in the DSL, instead of performing the same logic
redundantly in the shader.
In some cases this can be fairly significant, e.g. RectBlurEffect has
a global with the expression
abs(rect.x) > 16000 || abs(rect.y) > 16000 ||
abs(rect.z) > 16000 || abs(rect.w) > 16000
