All files contain the same add/remove buttons and a feature list.
These common elements are moved into the TaskTransformedParameters.ui file.
The same goes for the common OK Button that is used in a MultiTransform.
The ui files for the patterns only contain their distinctive
parameters. And the common ui files contain an empy widget that will
be filled with the respective parameter widgets from the patterns.
- Since realthunder's contributions some months ago, the 4 pattern features (mirror, linear, polar, mulitransform) can handle several features at once.
This PR allows to select multiple features when creating a pattern.
(This speeds up the workflow because at the moment one has to create the pattern with one feature and subsequently add more.)
- fix dialog issue that Add and Remove button could be active the same time
- use the keyboardTracking feature to avoid unnecessary recomputes (e.g. currently 3 recomputes when inserting "12.5" to the length field of linear pattern)
- fix wrong <extends> statement in .ui files (automatically spotted and fixed by Qt's Designer)
