Setting CKEditor width should automatically adjust resize_minWidth

[Wiktor Walc]

same applies for editor height.

Consider the following scenario: page with a column having fixed width 540px and padding 20px. Developer sets CKEditor width to 500px.

Now user entering text in CKEditor wants to change editor's height. What will happen? CKEditor will automatically resize to 750px (default resize_minWidth is 750px).

Instead of forcing developers to look for resize_minWidth and setting it to lower value than width, I think we should change resize_minWidth to width automatically if width has been set and is lower than resize_minWidth.

I see this actually a pretty common case and I've seen ​others complained of it in forum.
In effect it happens even there's no configured width/height, but whenever the start layout size of editor is somehow smaller than our default value (750px), in such case, by setting min_resize value to actual size will prevent editor from shrinking, so how about having a dynamic min_resize setting to 1/2 of the original size?

250 may be a too small value. So, let's make it simple (KISS), by simply readjusting resize_minWidth to the start width if it's bigger than that.
