 * 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 immediately 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 different requirements, e.g. sequencer strip selection
 * also needs to account for handle selection. This should be the baseline behavior though.
