The presentation check on the leftover wheel fraction ran only while the
canvas was hovered and fitted, so switching to another presentation from
the tabs and back kept the old fraction. It now runs every frame the canvas
draws a presentation, before the hover and overflow branches.
Test: 0.75 of a line in one presentation, a switch away and back with the
pointer off the canvas, then 0.25 does not turn the page.

The leftover fraction of a wheel line is now stored with the active
document's uid and dropped when another presentation becomes active, so a
quarter line left in one deck can no longer turn a slide in another.
Test: 0.75 of a line in one presentation followed by 0.25 in a new one
does not turn the page; a whole line in the new one does.

High-resolution and free-spin wheels on Windows send fractions of a line
(e.g. 0.125 per event); rounding each one up turned a single notch into
several slides. The fractional line delta now accumulates in ui.data temp
state, resets when the direction changes, and each whole line is one
slide. slide.go is skipped when the target is the current slide.
Test: eight 0.125-line events turn exactly one slide, and a reversal
drops the leftover fraction.
