// Takes an image and pads it to fit a larger image, or crops it to fit a smaller one
// (although the latter is implemented slightly less efficiently, and you cannot both
// pad and crop in the same effect).
//
// The source image is cut off at the texel borders (so there is no interpolation
// outside them), and then given a user-specific color; by default, full transparent.
//
// The border color is taken to be in linear gamma, sRGB, with premultiplied alpha.
// You may not change it after calling finalize(), since that could change the
// graph (need_linear_light() etc. depend on the border color you choose).
