[Enhancement] E-book viewer: new mouse actions for the View image window

[etc205]

1. Perhaps click-and-dragging in the View image window in case it's too small to display the whole image (see the attached picture) should change the mouse pointer to "hand" and scroll the view: aiming at the vertical and horizontal scroll bars (outlined in red in the picture) and dragging them is rather a slow and awkward process.

2. Double-clicking on the image should perhaps close the View image window, since double-clicking on the image in the book opens it.

Calibre version: 5.16,
OS: Windows 10 Home 1803.

P.S. Please don't mind "Fit image" being outlined in blue in the attached picture, it has to do with a previous edition of this message and I didn't want to confuse people reading it by cluttering the thread with another attachment.

Fixed in branch master. The fix will be in the next release. calibre is usually released every alternate Friday.

Thanks for implementing 1). May I know know the reason for 2)'s (double-click closing the View image window) not having been implemented?

[etc205 (etc205)]

Actually, I know think it was a bad idea.

In the first edition of my first message I suggested two variants for the double-click action:
a) Closing the View image window.
b) Toggling the "Fit image" checkbox.

What would you say about b)?

Since #1926851's status is Fix Released now, there's probably no need for continuing this tread.
Thanks for the implementations.
