doc: Updates and fixes for docks and windows
Updates and fixes for the 2. Main Windows
sections in Part I.
Not as much work as I feared, but hopefully nothing was missed.
- Bring docks up to date with changed placement in gimp@2d071a08
- Note that a window arrangement is the most basic
for multi-window mode
. I would say the one-window mode is simpler still. - slider -> scroll bar where the text is about a scroll bar.
- general small parentheses, spacing fixes etc.
v2: dialogs dock
-> dock
for greater consistency between strings.
v3: The Inactive Padding Area
description stated that the inactive padding area separates active image display and the inactive padding area
. Change the end of this to the rest of the user interface
so it makes more sense.
