Revert "Move a line into try block"

This reverts commit 33b5bd16d5571b2ac4d19d81ba3640675628bf0a.
Display Settings: Better font size control

Use a SeekBar instead of a list/spinner to determine the font scaling.
For consistency, an approximate size (small, normal, etc.)
 and the exact percentage are displayed.
Show a preview of the selected font size immediately
