Feature #75: Invert window color
- Add window color inversion (--invert-color-include). It means 2-3
times extra painting, so performance issues are likely to appear. I
hope I could find a faster way to invert colors.
- Rename some functions.
- Fix update of some window properties after window type/data change.
Hopefully this will be helpful for #73.
- Split win_build_picture() from win_blur_background().
- Correct memory leak of ps->focus_blacklist during reinitialization.
- Add win_upd_t and win_upd_run(), to reduce duplicate window property
updates. But is unused right now.
- Limited tests are done overall. Bugs to be expected.
