bac8080b0c Typecast Levels to be float 
This circumvents cases in which "levels" is a boolean array and therefore the substraction fails due to deprecation.

c247aa3989 Fixed PySide image memory leak 
PySide has a known memory leak issue when using QImage. It does not handle the reference counter correctly. I manually adjusted the reference counter to the data as suggested in a bug report by Neil Whelchel. This bug report can be found at https://bugreports.qt.io/browse/PYSIDE-140

6b798ffed8 Fix multiple spinbox problems: 
- fixed bug with exponents disappearing after edit
 - fixed parsing of values with junk after suffix
 - fixed red border
 - reverted default decimals to 6
 - make suffix editable (but show red border if it's wrong)
 - revert invalid text on focus lost
 - siPrefix without suffix is no longer allowed
 - let user set arbitrary format string
