I'm working on a plugin that has a lot of control points in the image. I want to be able to link all the control points to a tracker, so they follow the image around, so I added a Matrix4 in the GUI.
How do I get my points (XY_knobs) to move around with the matrix? I hacked something together to update the transformation matrix inside draw_handle, but there's gotter be a better, more streamlined way of doing this? - Also because I have to invert the matrix to let the use move the point around in my handle function. What is the prober way to do this? Michael
