wmaker/WINGs/wcolorpanel.c
John D Pell bd38778bef Use wuserdatapath() everytime it is applicable 
Replace calls to wusergnusteppath() which just append "/Library" by calls
to wuserdatapath().
Take opportunity to replace hardcoded "/WindowMaker" directories with
the existing PACKAGE_TARNAME macro (which comes from autotools).

The choice of 'TARNAME' is because it meant to be used in filename, thus
less likely to have problematic characters than PACKAGE_NAME (meant for
display purpose) and PACKAGE which is there for historical reason.

Raw Blame History

/*
* ColorPanel for WINGs
*
* by ]d : Original idea and basic initial code
* Pascal Hofstee : Code for wheeldrawing and calculating
* colors from it.
* Primary coder of this Color Panel.
* Alban Hertroys : Optimizations for algorithms for color-
* wheel. Also custom ColorPalettes and
* magnifying glass. Secondary coder ;)
* Alfredo K. Kojima : For pointing out memory-allocation
* problems and similair code-issues
* Marco van Hylckama-Vlieg : For once again doing the artwork ;-)
*
*/
/* TODO:
* - Look at further optimization of colorWheel matrix calculation.
* It appears to be rather symmetric in angles of 60 degrees,
* while it is optimized in angles of 90 degrees.
* - Custom color-lists and custom colors in custom color-lists.
* - Stored colors
* - Resizing
