"No valid area for noise map specified" in preset browser laf

[David Healey]

Trying to add noise to my drawPresetBrowserColumnBackground laf function using g.addNoise() but get the error "No valid area for noise map specified"

I just went to the source to look into making an addNoiseToArea function and what do I find but sneaky undocumented HISE goodness.

You can pass an object to g.addNoise!

g.addNoise({alpha: 1.0, scaleFactor: 1.0, area: obj.area, monochromatic: true});

alpha = noiseAmount
