Replacing the color picker with a Hue-Saturation color wheel. (#695)
* first workable version of a colorwheel * don't stretch it too big smaller screens * better touch/drag behaviour + some properties centralized * changed coordinate system, dragable marker * little tweaks and cleanups * touch drag color tooltip * Segments, color via attribute, throttling, CSS-styling, small fixes * inmproved segment behaviour * styling with css vars/mixins * structuring, commenting and cleanup * properly prevent user select * don't import debounce * settled on some default color segmentation and wheel styling * getting rid of the hidden #wheel element just set css vars on the backgroundLayer and get those via getCumputedStyle * remove the #wheel css declaration too * width is just a stupid word that looks too much like with * move the color circle/tooltip a bit higher * quote all attributes
