In gimp_tool_options_manager_tool_changed() make sure the new tool's
tool options GUI always exists, so tools can access it even if the
tool options dockable is not currently open.
(cherry picked from commit c3752ba743)
tool_options_manager_tool_changed(): also copy the non-global paint
options of the new tool to the global paint options, so they get used
when "global_foo" is enabled.
(cherry picked from commit 1b858eb4ad)
tool_options_manager_paint_options_notify(): sync properties between
tool paint options and global paint options if the property is global
*or* the active tool is involved.
tool_options_manager_global_notify(): don't mess with the active
tool's connection to the user context or its properties at all, it is
always fully connected to the user context anyway.
(cherry picked from commit 54257da7c4)
The way we currently manage tool options, and particularly copy things
around for "global_brush", "global_pattern" etc. sucks, is spread
across files, happens only on tool change, is thus buggy and leads to
all sorts of small inconsistencies.
This new manager will replace all of that stuff, and it does it in one
place, and will keep the user context, the global paint options, and
all tool options connected permanently, and only connect/disconnect
things when settings change, so everything is always in a consistent
state.
Pushed for review only, nothing is used yet.
