QML resource dropdown fixes

Carsten Hartenfelsrequested to merge
hartenfels/krita:feature/textflick into master

QML ListView can normally be scrolled by dragging it. The text properties CSS preset and font family delegates use a mouse area that break that behavior, effectively making the list views not scrollable on touch screens unless you somehow intuit that pressing all the way on the right edge will operate the invisible scroll bar.

This just removes the property that prevents the drag scrolling, which seems to have no adverse effect otherwise.

It also scales the drop-down arrow properly under high-DPI scaling.

Test Plan

  • Look at the arrow of QML resource drop-downs on a high-DPI screen. Observe that it's not crunchy anymore.
  • Open the font families drop-down in the text properties docker or the style preset drop-down in the text tool settings. Drag around on the list. observe that flick scrolling works now.

Formalities Checklist

  • I confirmed this builds.
  • I confirmed Krita ran and the relevant functions work.
  • I tested the relevant unit tests and can confirm they are not broken. (If not possible, don't hesitate to ask for help!)
  • I made sure my commits build individually and have good descriptions as per KDE guidelines.
  • I made sure my code conforms to the standards set in the HACKING file.
  • I can confirm the code is licensed and attributed appropriately, and that unattributed code is mine, as per KDE Licensing Policy.
  • Does the patch add a user-visible feature? If yes, is there a documentation MR ready for it at Krita Documentation Repository?

Reminder: the reviewer is responsible for merging the patch, this is to ensure at the least two people can build the patch.
