UX Changes

For Edit Viewer:

• Added support for panning images in textSelection mode.
• Text markup annotations can be modified after being cropped.
• Return to pan mode if textSelection mode is turned off on mobile by clicking the icon.
• Added support for returning to pan mode by pressing ESC.

For Edit Viewer and Browse Viewer:

When the cursor is around the viewer’s edges when selecting text or dragging the thumbnails, auto-scrolling will be triggered. It can be configured using the enableAutoScrollForTextSelection property for Edit Viewer and the enableAutoScrollForDragPages property for Browse Viewer.
