a slider snaps to its step, a pushed button releases, and warnings show

- a slider with a value step snaps to it: a stepped drag fires once per row instead of once per pixel, a scrollbar cannot rest between two rows, and one wheel notch on the trainer list reaches the bottom (2133)
- setting a step on a live slider moves its value onto the new lattice and runs its handler, which an addon on the real client can count on (2143)
- a button pushed from script releases on the next mouse-up, so Tablet-2.0's rows stop staying pressed forever; a release off the button's rect un-presses it, and a locked state holds (2134)
- the mail body and the GM ticket box scroll as you type past their bottom, and the Use UI Scale checkbox reads a registered setting (2141)
- an engine warning, a call that was accepted and did nothing, reaches the /errors window in grey instead of one terminal line; a text row trimmed mid-character no longer kills the window's repaint (2135, 2138)
