Crop to size + Fit to size
Two simple nodes that are missing and make hellsome macros.
Crop to size - Just like the built-in crop, except that it always outputs to its defined size, ie if the image size is smaller than the crop size, this node pads it out with rgba 0,0,0,0.
Fit - Takes an image input, scales it to completely fill its defined size, then crops any excess resulting from mismatched aspect ratios. voila: your input now fits the defined size.
