Sync 2Geom to commit 5ee51c1c4f2066faa3e2c82021fc92671ad44ba4

static code analysis

Fix calls to Geom::cross() - sign change.

2Geom sync - initial commit

i10n. Fix for Bug #1429579 (Various typos in the trunk code).

more cast cleanup

corrected the casts (hopefully)

Put a few std::vector<SPitem*>

At first, I was thinking "I just have to go to the selection file, and change that GSList* with a std::list, then resolve the few problems" So, i tried that. And I will continue tomorrow, and the days after, on and on.

Update to experimental r13565

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

fixes to LPEKnot, now usable again. knotholder: if knot coords are non-finite, hide knot. used for hiding the lpeknot switcher knot if there are no crossings

Properly allow effect stacking with knotholders (and add extra LPE functionality)

Removed some operator keywords.

lpe knot: code cleanup. mostly adding parens to if-statement predicates that relied on operator precedence

fix hiding overloaded virtual

const ....

Fix "shift disables snapping" for LPEs and for editing objects

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

Removed outdated classes. Pruned header to not introduce extraneous includes.

Adding base configurable sizing of controls/handles.

Warning cleanup

cleanup knotholder code for LPEs

Header cleaning

turn SPPath into a class, and add some methods...

cppcheck

cppcheck

Doxygen cleanup.

Cleanup of oudated/redundant SP_ITEM() macro use.

Added some mnemonics for filter path effects (Bug #170765)

update to latest 2geom !

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.

LPE Knot: only consider closing line segment if its length is non-zero

fix lpe knot for closed paths

UI fixes (a.o. Bug #560751 )

SPShape c++ified to the extent it was possible and more changes done for XML privatisation. Major changes yet to come.

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

lpe-knot: fix crash

decrease header deps

Patch by Johan to fix 365903.

Deweirdification of user visible messages as proposed by Tav

comment out debug output

bug fix about closed path.

knot lpe: enable groups + cleanups/simplifications

Warning cleanup.

bug fix: handle paths with more than one component.

hatches lpe: parameters renamed + tips, knot-lpe: can use 'unit of stroke width'.

double inclusion fix

Merge from fe-moved

From trunk

Merging from trunk

lpe-knot update. Each crossing can be flipped independently.

fix for 2geom change (pointAndDerivative)

copyedit

- try to use more forward declarations for less dependencies on display/curve.h - change _bpath to private member of SPCurve, obtain and set with get_bpath and set_bpath. - added const methods, so protect changes to _bpath in SPCurve

change doEffect functions to use const& parameters

lpe-vonkoch: complexity bound + choose bbox/segment as reference. lpe-knot: support for self intersecting bezier (will be moved to 2geom).

skeletal-stroke: offset parameters are back again... optionaly proportional to pattern size.

Whitespace cleanup

3 new lpe gadgets: sketch, knot and vonkoch.
