* Fix the "Enable debug logging" checkbox so that it properly disables "Enable verbose debug logging" when it gets disabled * Avoid asking ImageWidget for alpha-blending when it's not useful * Make ImageWidget's alpha-blending code-path double-check that alpha-blending actually is needed, and avoid it if possible * In the same vein, only do alpha-blending in textboxwidget when absolutely necessary * Prefer color constants over the gray() method, ensuring that they're part of the eInk palette Depends on https://github.com/koreader/koreader-base/pull/853 Fix #4774
