-/**
- * This class is used to communicate the particular GrEffect used in a draw to the backend-specific
- * effect subclass (e.g. GrGLEffect). It is used to by the backend-specific class to generate a
- * cache key for the effect, generate code on a program cache miss, and to upload uniform values to
- * the program.
- * In addition to the effect, it also communicates any changes between the relationship between
- * the view matrix and local coordinate system since the effect was installed in its GrDrawState.
- * The typical use case is that sometime after an effect was installed a decision was made to draw
- * in device coordinates (i.e. use an identity view-matrix). In such a case the GrDrawEffect's
- * coord-change-matrix would be the inverse of the view matrix that was set when the effect was
- * installed.
