Get pollar tiling working agains with trunk

Migrate remaining dialogs to Gtk::Grid

Further migration to Gtk::Grid

Convert a load more C-style pointer casts to GObject or C++ casts (merry christmas\!)

code cleanup: make more functions static or include their own headers.

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

Renamed files to better match coding conventions

Fixed runtime assertion about Parent beeing Null

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

Added first support for elliptical arrangements

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

Added some POC code to move objects around

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

Changed enum used for alignment, which hopefully will fix daily deb builds.

Anchor widget now reads the last alignment from the settings. Anchor selection widget is also smaller now.

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

Removed some commented code, which i replaced, and is therefore no longer used.

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

Header cleaning

(cppcheck and janitorial tasks:) C-style casting to C++-style casting

More deprecated GtkTooltips

increase max values in rows&cols dialog. increase significant digits

Refactor SPItem bounding box methods: remove NRRect usage and make code using them more obvious. Fix filter region computation.

- rename SPItem::i2d_affine to i2dt_affine, to clarify that it is item-to-desktop, not item-to-document. This should make it easier to spot bugs. - tag some instances where the document-to-desktop transform has been hardcoded

Remove more of libnr

Use generic headers in preparation for GTK+ 3 transition

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

Finished cleanup of outdated SP_OBJECT_REPR C macro.

update to latest 2geom !

Mnemonics in "Export bitmap", and "Rows and Columns" dialogs (Bug 170765)

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.

New Class SPDocumentUndo created which takes care of c++fying some non SPDocument based methods

C++fied SPDocument added

This is the first c++ification commit from me. It handles sp-line, sp-polyline, sp-item and marks the onset of document c++ification as well. Users can check performace increase with [/usr/bin/time -v inkscape_binary_with_commandline_options].

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

Separated "Arrange" as button caption from "Arrange" as menu item

Make all icons themable (except the filter icons).

Fix some console warning spam (most cannot be fixed, unfortunately)

Warning and whitespace cleanup.
