Update to experimental r13565

Update to experimental r13543

Formatting

More header cleanup

Cleaned up a bit; fixed struct vs. class forward declarations.

Fixing regression

Working with widjets

Fix even more forward declaration tags

Header tidying, suppress all gdk deprecation errors in gtkmm

actually fontforge flipping of y-axis for svgfont glyphs is compliant with the svg spec. So we need to do it also.

fix rendering of SVG Fonts. Apparently the glyphs were wrongly rendered upside-down since I was trying to make it compatible with fontforge rendering. Now, reading again the SVG spec, it seems to me that it is fontforge that renders it incorrectly. I have also added support for rendering path tags that are children of glyph and missing-glyph nodes. And also use tags. But fontforge does not seem to understand use tags in glyph descriptions... compatibility issues that we have to figure out how to solve.

updating my email address in file headers

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

Merging from trunk

fix crash on svnfonts dialog

* removed the auxiliary GtkWindow * added font preview to the SvgFonts dialog

Fixed compilation when the new SVG font stuff is not enabled.

* started implementing rendering of SVGFonts horizontal kerning

* implemented text_to_glyphs, so that now we can have ligadure glyphs * Adapted example file to test this feature too

* converted nr-svgfont.cpp to C++ code so that we can render multiple instances of fonts. Currently we have one auxiliary GtkWindow for each <font> in a document. * Implemented C++ binding for cairo userfonts. This will probably be sent to cairomm soon. * Added a second font to the svgfont.svg test file.

* 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.
