Closed Unassigned: _themeTint default value must be 0 instead of 1 [9336]

Hi,

In the class XLColor_Internal.cs on line 53, _themeTint is currently initialized with the value 1.
However, the default value should be 0, hence:
___themeTint = 0;__

_themeTint will receive a value between -1 and 1:
"1.0 means 100% lighten. Also, _0.0 means no change_."

I do see some checks on ThemeTint != 1 throughout the code which I belief are not required if the initialization of _themeTint is fixed.
Comments: fixed
