In my experiments, when jit.gl.multiple's target is any GL object other than jit.gl.sketch, multiple's glparam for color functions as expected. However, when multiple's target is sketch, the color from sketch is inherited onto the rendered shapes and multiple's glparam for color is not applied.
I've tried to make this test patch as simple as possible to demonstrate my meaning.
I feel I must be doing something silly here. What am I missing?
