Trying to make a jit.gl.pix patch to give me a circle of high alpha with a soft-edge blend to zero alpha at the circle's edge. Think I've worked it out, but I'm getting some compile errors with my solution which seems to me as if its fine:

The problem is a bug in jit.gl.pix that doesn't convert some constants to a float representation like they should be. GLSL is really strict about this. Here's a less than ideal workaround:

Hi David,
