Change Details

This patch is part of task T8708, focused on further improving Krita's color picker. >As of right now, Krita effectively has two near-duplicate paths when it comes to color picking code: the code for the dedicated Color Selector Tool (P) exists mainly in "kis_tool_colorpicker", while the code for the ctrl-key activated color picker that you can pull up while other tools are active [as well as the scratchpad's picker] exists mainly in "kis_tool_utils". This patch addresses this issue by, as much as possible without some much bigger changes, unifying all of the core color picking functionality within the `KisToolUtils` namespace's `pickColor` function. Essentially all of the duplicate code was removed from `kis_tools_colorpicker`, which now calls into the same `KisToolUtils::pickColor` function that's used elsewhere creating a single place in the code where things like sampling radius and color picker blending are implemented. As a result, any change to the code in `KisToolUtils::pickColor` will now affect all of Krita's color pickers (the dedicated tool [P], the ctrl-activated picker, and the scratchpad picker) in a uniform and predictable way. While this patch does solve the most of the code-duplication issue that existed in Krita's color pickers, there are still a few ways in which the dedicated tool and the ctrl-picker behave inconsistently. In my view, more extensive refactoring can be done in the future to create more uniform and predictable behavior across the various pickers, resulting in more color picking code being moved into `KisToolUtils::pickColor` from elsewhere. For now though, I wanted to focus on code-reuse improvements that don't have any user-facing design implications.
