reading of various skin setting values.
For instance:
- OK
FontSize=10
FontSize=0
- NG (uses default value instead)
FontSize=
FontSize=ABC
FontSize=20ABC (has been parsed as "FontSize=20" until now.)
- CHANGED: FontSize=0(invisible) is now able to use in Meter=STRING.
- Fixed the problem that the window doesn't move into the screen correctly when KeepOnScreen is 1.
