### Painting
* [ ] Pixel-perfect painting (round positions to nearest pixel).
* [ ] Make sure alpha blending is correct (different between web and glium)
* [ ] sRGBA correct colors
### Animations
Add extremely quick animations for some things, maybe 2-3 frames. For instance:
* [x] Animate collapsing headers with clip_rect
### Clip rects
* [x] Separate Region::clip_rect from Region::rect
* [x] Separate Ui::clip_rect from Ui::rect
* [x] Use clip rectangles when painting
* [x] Use clip rectangles when interacting
* [x] Adjust clip rects so edges of child widgets aren't clipped
