User needs to be able to cancel long render operation

Original Redmine Issue: 7126
Affected QGIS version: master
Redmine category:map_canvas

---

During a render that is taking a long time, the user has no opportunity to cancel the operation.

There should be either a dialog box with a cancel button presented, or the keyboard should be scanned for presses of the Esc key.

Otherwise there is only the option of force quitting the application and losing unsaved changes in the current project.

near the bottom right of the qgis window you have a "stop rendering" button, does this work for you?
