Runtime SkSL: Reflect inputs in SkRuntimeEffect Adds a new structure to describe the inputs, including type, shape, name, etc. This removes any references to the type variables in the compiler's context, and centralizes the logic for parsing those type variables. Also normalizes the rules for what types are supported. (This was inconsistent among the various functions before). Now: - bool and int must be 'in' - float may be 'in' or 'uniform' - float[2-4] and matrices must be 'uniform' Includes a new Slide that allows for interactive editing of a runtime shader.

#include "include/effects/SkRuntimeEffect.h"
Handle runtime effect shader errors better - Expose shader error handler on GrBaseContextPriv - Use that to report errors that happen during (late) SkSL conversion - Remove various asserts. We expect these functions not to fail, but they absolutely can for any kind of error that gets past the first compile in SkRuntimeEffect::Make. We'll still make a GLSLFP, but it won't inject any code, so the resulting shader will *also* fail to compile. Injecting our own errors first gives the user a better idea what's actually broken. - SkSLSlide also reports errors via the error handler now, too.
