- /*
- * TODO: Move textures and buffers to the iterator model used by coords.
- * We now want to find the subset of samplers that belong to the child and its descendants and
- * put that into childSamplers. To do so, we'll do a forwards linear search.
- *
- * Explanation:
- * Each GrFragmentProcessor has a copy of all the textures of itself and all procs in its
- * subtree. For example, suppose we have frag proc A, who has two children B and D. B has a
- * child C, and D has two children E and F. Each frag proc's textures array contains its own
- * textures, followed by the textures of all its descendants (i.e. preorder traversal). Suppose
- * procs A, B, C, D, E, F have 1, 2, 1, 1, 3, 2 textures respectively.
- *
- * (A)
- * [a1,b1,b2,c1,d1,e1,e2,e3,f1,f2]
- * / \
- * / \
- * (B) (D)
- * [b1,b2,c1] [d1,e1,e2,e3,f1,f2]
- * / / \
- * / / \
- * (C) (E) (F)
- * [c1] [e1,e2,e3] [f1,f2]
- *
- * So if we're inside proc A's emitCode, and A is about to call emitCode on proc D, we want the
- * EmitArgs that's passed onto D to only contain its and its descendants' textures. The
- * EmitArgs given to A would contain the textures [a1,b1,b2,c1,d1,e1,e2,e3,f1,f2], and we want
- * to extract the subset [d1,e1,e2,e3,f1,f2] to pass on to D. We can do this with a linear
- * search since we know that A has 1 texture (using A.numTexturesExclChildren()), and B's
- * subtree has 3 textures (using B.numTextures()), so we know the start of D's textures is
- * 4 after the start of A's textures.
- * Textures work the same way as textures.
