[Feature suggestion] Extend the context menu, upon right-mouse button click, via "Image -> Resize" (and possibly more options, in a submenu)

[rubyFeedback]

Current behaviour:

If you click via the right-mouse button onto the main widget, e. g. the one that shows the image, the following pop-over is shown:

"Select all" "Import" "Paste"

I assume you cater to "normal" folks, aka casual users, so showing not too many options is fine.

However had, I would like to specifically have a quick shortcut option here, a fourth one, that would say:

"Resize image".

As this is a task I do often.

But, other users may not need this. So, how if we could add a fourth option, that would simply say:

"Additional options"

And then, in that fourth option, we add some more common image operations. Including resizing images.

I don't know which options we should show there; perhaps the top-ten most commony use cases, or if you want to, additional sub-menus for such options, e. g. "File -> " and then under File, options such as resize (or, Image -> Resize). And perhaps we can also have an entry "Image -> Filters", to apply blur-like filters. And sharpen-filters. These are things I am used by gimp. Probably we could simply re-use ImageMagick for such filters, so Drawing does not have to implement everything on its own and can just delegate to ImageMagick. Anyway, that's a later idea; perhaps for now, could we consider the option to show one more entry when clicking the right mouse button, and in that new pop-up, group some more actions? Sometimes using the right mouse button can be more convenient, such as when you have a wide monitor and need to move a lot, whereas with the mouse cursor, we can just click anywhere, as-is. At any rate thank you for reading - hopefully you can understand the gist of this issue request.
