Performance issuses

On a volume knob with 100 values and a low kSwipeSensitivityPixels (below 20), the knob doesn't work properly with a custom .png drawable or with the pop up balloon enabled. Disabling the drawable and using flat colors for the knob parameters fixes the issues. The biggest issue it that the problem still persist when the drawable is set to app:kKnobDrawableRotates="false" which means the image is static and there is no need to redraw it.

Thanks for a nice library.
