		* Selecting and tweaking items are overlapping operations. Getting both to work without conflicts
		* requires special care. See
		* https://wiki.blender.org/wiki/Human_Interface_Guidelines/Selection#Select-tweaking for the
		* desired behavior.
		*
		* For default click selection (with no modifier keys held), the select operators can do the
		* following:
		* - On a mouse press on an unselected item, change selection and finish immidiately after.
		* This sends an undo push and allows transform to take over should a tweak event be caught now.
		* - On a mouse press on a selected item, don't change selection state, but start modal execution
		* of the operator. Idea is that we wait with deselecting other items until we know that the
		* intention wasn't to tweak (mouse press+drag) all selected items.
		* - If a tweak is recognized before the release event happens, cancel the operator, so that
		* transform can take over and no undo-push is sent.
		* - If the release event occurs rather than a tweak one, deselect all items but the one under the
		* cursor, and finish the modal operator.
		*
		* This utility, together with #WM_generic_select_invoke() and #WM_generic_select_modal() should
		* help getting the wanted behavior to work. Most generic logic should be handled in these, so that
		* the select operators only have to care for the case dependent handling.
		*
		* Every select operator has slightly diferent requirements, e.g. VSE strip selection also needs to
		* account for handle selection. This should be the baseline behavior though.

		* #WM_generic_select_modal()), so that the exec callback can be called a second time on the
