Fix unnecessary inclusion of glibmm/threads.h. This can be resolved by ensuring that glibmm headers always preceed glib.h headers. Same applies with gtkmm/gtk+ etc

Added configure/ifdef guards to only bring in the needed #include if glibmm has it.

Correct to compile against recent gtkmm, including updated macports versions. Fixes bug #1179338.

Migrate remaining dialogs to Gtk::Grid

Further migration to Gtk::Grid

Fix for 747998 : Align unit menu in Rows Columns dialog

The Polar Arrange Tab of the Arrange Dialog now hides the parametric controls until the user selects the corresponding radio button

Code Refactoreing. Moved parts of the code from tile.cpp tile.h to arrangetab.h, gridarrangetab(.cpp|.h), polararrangetab(.cpp|.h) Also modified the name of the verb used by the "Rows and Columns" dialog to SP_VERB_SELECTION_ARRANGE

Improved UI of PolarArrangement Tab and connected some widgets to events (now parts of the GUI disable themselves when needed)

Improved User interface. Added controls for Center, Radius and Angles. Note that none of them actually do something yet

Added initial gui for polar arrangement tab

Brought old code, "Rows and Columns" in it's own class. Added a separate class for the panel. Still some cleanup to do.

Integrated the newly created Anchor-Selection-Widget with the existing "Rows and Columns" panel. Code still needs documentation and cleenup however.

Added anchor-selection widget, it doesn't do much at the moment, next step will be to wire everything together, btw, you can see the widget in the 'rows and columns' panel

Clean up all remaining false warnings from Gtkmm

More deprecated GtkTooltips

change spinbox to new one in many places.

upgrade the spinboxes in tile dialog. (alignment is a bit awkward, have tried to fix it, but didnt work out)

Super duper mega (fun!) commit: replaced encoding=utf-8 with fileencoding=utf-8 in all 1074 Vim modelines. The reason for this is that (a) setting the encoding isn't nice, and (b) Vim 7.3 (with modeline enabled) disallows it and pops up an error whenever you open any file with it ("invalid modeline"). Also corrected five deviant modestrings: * src/ui/widget/dock.cpp and src/ui/widget/dock.h: missing colon at the end * src/ui/dialog/tile.cpp: removed gratuitous second colon at the end * src/helper/units-test.h: removed gratuitous space before a colon * share/extensions/export_gimp_palette.py: missing textwidth=99 That's my geekiest commit yet.

Fixed use of dialogs in more than one window, and tile problem with selection. Fixes bug #556233.
