Quad Resizing

Hi

I’m trying to develop a multi-touch interface (aren’t we all?)

my issue atm is that when i resize a quad…it resizes from the center and both edges move out from that center point. WHat i want to happen is for one edge to stay in place…and the quad to expand to the other edge. for example i “hold down” the left edge…and then “move” the right edge to make the quad larger

try to develop a subpatch which uses some standard math nodes like + - / * to build your own tranformation node which uses the bounding box coordinates x1, y1, x2, y2 instead of x, y, w, h.
