Allow disabling resize handles when using resize buttons

[jodator]

Provide a description of the task

The ImageResize plugin was refactored to common glue plugin that requires:

• ImageResizeEditing - for command and image resize handles
•  ImageResizeUI - for dropdown and buttons

However, we've identified that not everybody would like to have buttons and resize handles and it would be nice to configure ImageResizeEditing feature so that handles are optional (as opt-out to have backward compatibility if possible).

I can see two options:

1. Split the ImageResizeEditing to two - but the question remains how to name the resulting plugins (and how to keep backward compatibility for previous ImageResize plugin - or introduce breaking change.
2. Use configuration option, ie: config.imageResizeHandles: false (or similar).

What about this:

ImageResize: requires = [ ImageResizeEditing, ImageResizeHandles, ImageResizeButtons ]

Right now, you enable ImageResize and that will still work.

If you'll want buttons only – you'll load ImageResizeEditing + ImageResizeButtons

If you'll want handles only – you'll load ImageResizeEditing + ImageResizeHandles

Do I miss something?

No, this is also a way to go. I like the naming, so probably it is a way to go :)

@Reinmar your granular approach is OK, but IMHO it'd be nice to have the opt-out option (config.imageResizeHandles: false) for handles as well if someone is already using the ImageResize plugin. I think it's convenient. Or is it too much?

We tend to have less config options if possible so configuring (opting-out) by plugins configuration in build would be OK.

Exactly.
