poire-z e1ba5ccffe Various minor fixes (#4172)
- css tweaks: use correct CSS "hyphens:" instead of "hyphenate:"
- screenshoter: more logical order of lines (no change in what it does)
- textviewer: make diagonal swipe really trigger a full refresh
- textwidget: more adequate text length to help with centering
- toggleswitch: fix sizing & centering with correct calculations
  (this reduces a bit the size of switches, and may cause a new
  truncation in some translations)
