ID 497015 - Double precision AColor_knob does not work

Problem summary
The default value of AColor_knob is overridden, when changing its variable type from float to double.

Customer reported version
Nuke 13.0v4

Customer reported platform
ubuntu

Steps to reproduce
1) Write a plugin containing AColor_knobs using both doubles and floats.

2) Set specific default values to exercise the initialisation.

3) Launch Nuke and load the plugin.

4) Notice that the float AColor_knobs will be set correctly (as defined in the default values).

5) Notice that the double AColor_knobs will not be set correctly (as defined in the default values).

Expected behaviour
The knob values should match the default values set for both floating point and double precision knobs.

Actual behaviour
The knobs values are set incorrectly for double precision knobs.

Workaround
Currently only floating point AColor_knobs work. The only solution for double precision is to create custom knobs with the same behaviour.
