Code cleanup.

Replacement of unnecessary variables.

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

Merged more 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.

Fixing regression

Working with widjets

Drop checks for ancient dependency versions. These are satisfied elsewhere.

Various changes.

Header cleaning

Finished cleanup of outdated SP_OBJECT_REPR C macro.

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.

Corrected string-to-number conversion to use locale-independent conversion and to handle missing/null values. Fixes bug #544833.

updating my email address in file headers

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

SPDocument->Document

Now users can design a font within inkscape, save it and then open the SVG file in Fontforge in order to export a truetype font (or other system font formarts fontforge supports). This improves previous workflow of font design using Inkscape which involved creating one SVG for each glyph. Now user only needs to create a single SVG file containing an SVGFont. Glyph kerning settings for the font can also be defined withing Inkscape itself with live preview. The kerning management still needs some improvements but is currently functional at least. Improvements in the SVGFonts dialog: * In Global Settings tab you can define the font family name. Other attributes should be added to this tab in the future. * Glyphs tab allows the user to: ** see a list (combobox) of glyphs available in the currently selected font. ** add/remove glyphs ** edit glyph name and unicode ** set the glyph curves based on a given path (selected from canvas). Same feature for the missing glyph. * Kerning tab allows user to: ** add new kerning pairs ** adjust kerning values of selected kerning pair ** live preview while adjusting the kerning values Code refactoring: * Inner classes DocumentProperties::SignalObserver and FilterEffectsDialog::SignalObserver were duplicated code and another instance would be needed in SVGFonts dialog. So, I moved it to Inkscape::XML::SignalObserver (in helper-observer.{cpp,h}) * changed SPGlyph->glyph_name and SPGlyph->unicode from char* to Glib::ustring * added sp_remove_resource to the release method in sp-font.cpp * glyph curves used to be stored (in d attribute) and rendered upside-down. Now that bug is fixed. Sorry about this huge commit. I got one week away from the Internet during a xmas travel. The lack of 'net connection made me work more intensely in Inkscape :-D Felipe Sanches

removing lots of g_warnings

adding ifdef HAVE_CONFIG_H

implement kerning by glyph-name, g1 and g2 attributes

UnicodeRange class implementation. This class represents a range of unicode codepoints as used in the u1 and u2 attributes of glyph kerning nodes.

plumb XML::Documents in everywhere

* add rule in configure.ac so that only who has cairo > 1.6.4 (currently cairo git master branch) will compile SVGFonts (experimental) support. * First code for SVGFonts rendering. Renders in a separate window because we still dont have pango integration.

distinguish between hkern and vkern tags

Starting Summer of Code: SVG Fonts * hkern and vkern: parameter loading.
