renamed SPPattern methods to match coding style

Allow editing of fill and stroke patterns simultaneously. Fixes #601336, #604025, #486192

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

SPPattern c++-sification: class fields are private

SPPattern c++-sification: replacing pattern_ functions by methods pt1

Further refactored SPKnot.

First step of refactoring SPKnot.

const ....

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

Header cleaning for GTK+3 migration

Adding base configurable sizing of controls/handles.

Fixing more broken and split doc comments.

- 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

Warning cleanup.

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.

- Constrained snap: proper implementation of the preference to snap the mouse pointer or handle itself (instead of projecting it first onto the constraint) - Fix a crash in SnapManager::multipleConstrainedSnaps

Clear pointers in the snapmanager if they're no longer needed.

Wholesale cruft removal part 2

- Snap while rotating an object using the selector tool - Rename the ConstraintLine class to SnapConstraint - Move some duplicated code to 2geom

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].

Revert the inverted coordinate system fix. 3D Boxes and guides require an XML-level backwards compatibility mechanism to fix properly, and it's too late in the 0.48 cycle to introduce it.

Fix pattern knotholder

Remove redundancy from snapping API (type of snapsource no longer has to be specified explicitly)

When dragging a knot along a constraint line, then allow snapping the position of the mouse pointer instead of its projection onto the constraint line (for this a check box has been added to the preferences dialog)

Remove an unused parameter from the snapping API

Implement constrained snapping when dragging the position and size handles of a rectangle in the node tool, with the ctrl-key being pressed.

* Implement constrained snapping of knots * Implement snapping of the rectangle's radius handles * Line snappers: set the snap target in the derived class instead of in findBestSnap()

The snap indicator's tooltip now displays "A to B", whereas before it only displayed "B".

More NR ==> Geom changes

From trunk

Merging from trunk

Modify the parameters required for setting up the SnapManager

Move all of the snapper code to 2geom

remove many unnecessary to_2geom and from_2geom calls

fix ambiguities by implicit NR::Matrix/Geom::Matrix cast.

Warning cleanup

when holding ctrl, pattern scaling has a fixed 1:1 ratio of original pattern size

2geomify a lot of NR::Points to Geom::Point

change knot.h to Geom::Point only instead of NR::Point.

Formerly static function used for snapping is now a private member of KnotHolderEntity

remove strange factor for showing the pattern unit cell (quarter of real cell).

patterns: make it possible to have different scaling in X and Y directions. snap scaling point.

enable snapping of pattern's origin

fix release mouse crash, add missed disconnects, remove unused callback

Enable simultaneous knotholder and nodepath

change NR::Matrix to Geom:: for many sp_item_xxx_affine functions

warning cleanup

Add missing file knot-holder-entity.cpp; sorry for breaking the buildsvn add knot-holder-entity.cpp
