…k#5161) * Closes emilk#5106 * Closes emilk#5084 Protect against rounding errors in egui layout code. Say the user asks to wrap at width 200.0. The text layout wraps, and reports that the final width was 196.0 points. This than trickles up the `Ui` chain and gets stored as the width for a tooltip (say). On the next frame, this is then set as the max width for the tooltip, and we end up calling the text layout code again, this time with a wrap width of 196.0. Except, somewhere in the `Ui` chain with added margins etc, a rounding error was introduced, so that we actually set a wrap-width of 195.9997 instead. Now the text that fit perfectly at 196.0 needs to wrap one word earlier, and so the text re-wraps and reports a new width of 185.0 points. And then the cycle continues. So this PR limits the text wrap-width to be an integer. Related issues: * emilk#4927 * emilk#4928 * emilk#5163 --- Pleas test this @rustbasic

Fix Issues: more and more Wrap are added every time the mouse is moved.
Using
floor()will cause the value ofwrap.max_widthto keep getting smaller.You should use
round()orceil()to prevent the value ofwrap.max_widthfrom getting smaller.
