Initial removal of box3d outdated GTKish macros.

Update to experimental r13565

Header cleanup: stop using Glib types where they aren't truly needed. Eases GThread deprecation errors.

Added some consts.

Add 3d Box displayName and description

Refactor status-bar text for multiple items, was very broken

Added runtime check in SP_-cast macros.

Modified SP_IS_ macros.

Fixed more mismatched-tags; replaced GObject-properties in SPGuide

Merged Group and subclasses.

Added constructors to SP classes.

Replaced all casting macros with glib-independent ones.

Renamed virtual function names.

Kill ancient gcc version check in configure.ac and fix a load of broken forward declarations

Added "virtual pad" to SPBox3D.

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.

More in XML privatisation with new create3DBox function and other supplements to efficiently hide information.

SPObject c++ification finalized along with the beginning of XML Privatisation tweaks

Major simplification of 3D box code.

More NR::Point ==> Geom::Point

Fix passing wrong pointer type when using the tweak tool on 3D boxes

Make grouped 3D boxes work correctly when transformed (fixes: LP 188991)

fix converting 3d boxes to path and ungrouping - do not lose selection, preserve style, id and clip/mask

Clean up comments and remove (already commented) debugging messages

Slightly more 'object-oriented' way to invoke item-specific conversion-to-guides methods

Add possibility to convert objects (only rectangles and 3D boxes currently) to guidelines. Also see corresponding post on the mailing list; in particular, feel free to revert it if this is inappropriate during Frost phase.

Convert 3D boxes to ordinary groups before tweaking, ungrouping or applying 'convert to path' (closes LP #179693 and #176646).

Recompute box corners relative to new perspective when merging persps (to prevent boxes from jumping randomly)

Don't show boxes as everted (i.e., always show the same sides) during initial drag, regardless of the mouse pointer position.

Bug fix: prevent perspectives from being transformed more than once (by keeping track of selected boxes and their transformations).

If necessary, split up perspectives when applying transformations to boxes; moreover, fix crash caused by listening to already destroyed perspectives

Fundamentally reworked version of the 3D box tool (among many other things, this fixes bugs #168900 and #168868). See mailing list for details. Sorry for this single large commit but it was unfeasible to keep the history.

Infrastructure to set direction of infinite VPs (now adjustable by some shortcuts; this may be removed later on)

Constrained center-dragging for 3D boxes (with Ctrl)

Various small cleanups

Rewrite of z-order code for 3D boxes, first stage (hopefully this is finally the right approach)

Enable center-dragging of boxes in Z direction by using Shift

Enable center-dragging of boxes ('in perspective') within the XY-plane

Fix behaviour of toggle buttons (for VP states) in 3D box toolbar; reshape boxes when state of a VP changes

Compute the correct visible front corner (also for 'upended' boxes) and set the z-orders accordingly so that they are correct for any relative position of the handles

Set z-orders of 3D box faces during dragging/resizing according to the perspective

Draw perspective lines; provide shortcuts to toggle their visibility and the corners where they are attached

Convenience for debugging

Write/read perspectives to/from SVG; store ratios of the distances from corners to VPs (preparation for dragging)

Write distinguished corners of 3D boxes to the svg representation from which the box can be recomputed. This is used to fix several bugs related to the editing of boxes resulting from cloning, undo operations or newly opened documents (we had stray pointers to SPPaths before that made Inkscape crash).

New/updated 3D box auxiliary/convenience functions (e.g., allow (un)constrained movement of corners, too; determine midpoints of edges)

Refactoring of 3D box internals. Handle the corners in the box itself and only link to them from the separate faces. This way we can make the code *much* cleaner and more generic. Provide generic auxiliary functions for the movement of corners in XY-plane and Z-direction.

Only create the faces of a 3D box when needed (use pointers to refer to them).

Use arrays to manage corners and faces of 3D boxes

First (very limited) version of the 3D box tool; allows for drawing of new boxes in a fixed perspective without any live interaction.
