Make non-mouse multi-clicks in KisTools work
By using the underlying KoToolProxy multi-click count instead of only looking for literal double-click events. Tablet and touch inputs don't have a separate double-click event, so e.g. the crop and polyline tool only reacted to them coming from an actual mouse. Now they work for all kinds of input, like they do for KoTools.
Test Plan
- Start an operation with the polyline or crop tool.
- Double-click with a mouse, tablet or touch. Observe that all three correctly react to the double click now instead of only to the mouse.
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. In case a patch breaks the build, both the author and the reviewer should be contacted to fix the build. If this is not possible, the commits shall be reverted, and a notification with the reasoning and any relevant logs shall be sent to the mailing list, kimageshop@kde.org.
