Sync 2Geom to commit 5ee51c1c4f2066faa3e2c82021fc92671ad44ba4

Header cleanup

Remove buggy and presumptuous usage of SP_ACTIVE_DESKTOP in renderer code; fixes 1526701

Fix crash on hidden guides

Clean up some code, only init the SPKnot in one place.

hide/show handle with guide

Remove CtrlPoint and replace with SPKnot

cppification : GHashMaps replaced by stl maps. getResouceList now gives a std::set<SPObject *>. Should give some performance improvements (quite a few linear lookups are now logarithmic)

Changed from Desktop to namedview to handle multiples documents

cppification: GSList replaced by vectors (mostly related to guides and grids)

Add global lock guides to the rulers

Added no highlight and cross icon on locked guides

Add lock to guides

Fix for bug #1498444 (Guides flicker under the mouse after changing the label of any guide) and bug #1469514 (Crash when renaming a guideline label in a new session).

Read inkscape:color attribute in more places

Read attribute after setting the default

Read inkscape:color attribute on guides

create SPObject factory

for snapping to grids and guides, reduce numerical error for the case of uniform scaling of viewbox

improved precision in placing grids and guides. (Bug 1373311)

Remove sp_desktop_document and finish cleanup of desktop-handles.h

Correct guide placement when created by dragging onto canvas or by creating guides around object/page.

Use SVG width/height and viewBox to correct guide position.

Units: make it absolutely clear that Document properties unit dropdown is for UI Display Units. Upon document load, calculate the units used for SVG values, if a viewbox is available. If not, default to "px" SVG units. Change all code to use either Display units OR svg units.

Fix annoying formatting in sp-guide.cpp

Refactor SPGuide to use more C++

Update to experimental r13565

Minor pass of header cleanup

Guides: Clean up memory a bit better and move color changed to OK so we don't set the colour before OK

Units: stop newing Unit objects. pass around pointers to "undeletable" Unit objects in the UnitTable. I think we should move to using indexed units, and pass around the index of the unit in the unittable, or smth like that... ?

Fix format security errors

Added viewBox implement document unit support.

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

Replacement of unnecessary variables.

Ported away from and removed "sp-metrics.*".

Back to original colors

updates to colors

Added prefPaths to contexts; modified SPFactory

Merge Object and subclasses. Merging of SP- and C-classes complete.

Merged more classes.

Merged FlowX classes.

Added constructors to SP classes.

Prepared exchange of casting macros.

Renamed virtual function names.

Removed function pointers from SPObject and subclasses. Added some missing virtual pads for classes that were hidden by preprocessor macros.

Added "virtual pads" to - SPFeFuncNode - SPFeDistantLight - SPFeMergeNode - SPFePointLight - SPFeSpotLight - SPFilter - SPFont - SPGuide Changes in SPItem and SPNamedView.

Various changes.

Fix build with C++11

Cleanup more GObject type definitions

fix XML output of guideline color (this does not fix loading of guide color)

Header cleaning

Completely remove NRRect, NRRectL, in-svg-plane.h

fix for bad argument crash for guides

Fix memory leak.

Fix issue with deleted guides and gtk warnings.

fix crash when guideline is deleted by dragging it off-canvas

another case of SP_ACTIVE_DESKTOP removed

remove some unnecessary inkscape_active_desktop() calls

revert unnecessary complicated change

refactor the guideline drawing. now it obeys desktop transforms a lot better.

Adding a "Remove All Guides" option to the Edit menu.

The label ‘Guides Around Page’ does not include a verb. ‘Guides Around Page’ what? 'Create Guides Around the Page' :-D http://cuts.thinking-garment.com/144

user interface for selecting colors of guidelines

add entry widget to guideline dialog to change guide's label (and fix some label xml writing and rendering bugs)

Adding inkscape:label parameter to guidelines so that our guidelanes can display labels (we still dont have a user interface, but files with that parameter will render correctly)

Finished cleanup of outdated SP_OBJECT_REPR C macro.

Split SPCanvasItem and SPCanvasGroup to individual .h files. Removed forward header.

Yet mor in c++ification

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

C++ification of SPObject continued along with the onset of XML Privatisation. Users may checkout [grep -Ir XML Tree *] in the source code and all the places where the XML node/Tree is being used shall be reflected.

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

C++fied SPDocument added

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.

Coords: fix guidelines

Revert recent refactoring changes by johnce because they break the build, which cannot be fixed easily.

SPDocument->Document

Implement guide behaviour as discussed on the mailing list

more detailed shortcut info

Change 'Effect' to 'Extension' in Extensions menu. Change capitalization of "Guides Around Page" for consistency.

display guide anchor on canvas; anchor and angle can be edited by mouse

From trunk

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

convert all SPCurve's points and matrices arguments and return types to 2Geom

fix 243913

try to use consistent document for creating guides

New menu command to quickly create guides around page

Also display guides as vertical/horizontal when they are angled at -90/180 degrees

Applying fixes for gcc 4.3 build issues (closes LP: #169115)

Display Ctrl+click option for guidelines in status bar message

copyedit

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.

fix angle description of guides

guidelines: minor corrections add point reading to repr-util.cpp

correctly handle orientation changes of guidelines

guides: switch from using one position coordinate to Geom::Point point_on_line

rename guide parameters to match snapping code naming convention. start conversion to use point_on_line instead of position.

start of getting angled guidelines. define guide's normal instead of vertical/horizontal. rendering is not implemented for angled guides yet.

warning cleanup

peeled back the gboolean code as it hit on some complexity theory principles... need to rethink and incrementally change gbooleans to bools

Ok, committed msgloan's patch to convert gbooleans to bools thus completing one major janitorial task we identified....

bulk trailing spaces removal. consistency through MD5 of binary

moving trunk for module inkscape
