[Feature Request] Enable Touchpad Support
On laptops with Touchpads, most have touchpads (not touch screens) enable support of using touchpad gestures for GThumb image control:
- allow zoom in selected full size image through two finger pinch and zoom (equivalent to mouse scroll and zoom that already works in the GThumb app, or Shift + F,X,H,W type),
- allow rotate in selected full size image through two finger rotate motion (Shift + R/L),
- allow swipe to next image left or right through two finger left or right swipe motion (left right cursor, or Shift + left/right cursor, or + up/down cursor) - similar to issue #161 .
