The OFX support code uses the flag Knob::READ_ONLY to disable colour knobs instead of Knob::DISABLED. This changes the behaviour when enabling and disabling the knob; if this is modified to use Knob::DISABLED instead, the colour picker and colour wheel controls are enabled and disabled along with the colour knob.
