Backout last commit as it introduced subtle errors.

SVG 2 allows 'href' without 'xlink:'. For now just read plain 'href'.

create SPObject factory

Fix build (not pretty).

When an externally linked image is modified, mark it for update instead of directly calling update() with a bogus ctx parameter. Prevents crash and fixes LP Bug #1278571.

Fix 'preserveAspectRatio' attribute of bitmap images in EMF/WMF import/export (bug #1278645).

Added new base class to handle viewBox and preserveAspectRatio. Updated sp-root, sp-symbol, sp-image, sp-pattern, marker to use new class. Fixed some viewport issues when % used.

Revert sp-image until the refactoring takes.

A partial refactor of sp-image.cpp, expect more.

Fix missing embeded image condition, kindly caught by suv in bug #1270334

More cleaning of the image tag handler and seperate filename from load.

Clean up sp-image's read_image, remove duplicate code

"fix" some "unused parameter" warnings

Added some consts.

if this->pixbuf check must come earlier to prevent crash

fix one code path where fullname wasn't freed

change names for displayName and detailedDescription, improve char code and remove const.

Drop unused static function declarations

Fix serious potential bug in SPImage::print

Remove a warning when embedding an image with a mimetype which is not directly handled by Cairo

Encapsulate the shared memory hack for Cairo and GdkPixbuf in a class called Inkscape::Pixbuf. Replace usage in the code as appropriate.

fix windows build

Do not recompress images when embedding and generating PDFs. Fixes blocker bug #871563.

Improve the functions which create GdkPixbuf from Cairo surface and vice versa. Simplifies some code. Also introduce proper refcounting into svg_preview_cache.cpp and fix its users.

better memory leak fix (fixes bug 986271: memory leaks associated with images) Patch by David Mathog, including revert of former fix in rev 11268

changes_2013_05_22a.patch: 1. Resolves issue of bug #988601 message 170 (Support of 'Unset' styles in EMF export). 2. Implements CSS 3 (and CSS 2) text-decoration support. Note that it does not yet provide any method of adding these features - at present it just shows whatever is in the SVG. This new code is also used to display EMF/WMF strike-through and underline text decorations when these files are read in. Those decorations may also be written out to EMF/WMF. Other text decoration features, like overline, or dotted lines, are dropped. For SVG text-decoration -line, -style, -color are all implemented. CSS3 provides two ways to represent the same state, this code uses the compound text-decoration method rather than the 3 fields method. Also it leaves out keywords that are not needed and would break backwards compatibility. For instance: text-decoration: underline solid is valid, but would break CSS2. Solid is the default, so that sort of case is written as: text-decoration: underline If the state is CSS3 specific all of the needed fields are of course include, like text-decoration: underline wavy red 3. It incorporates the fix for bug 1181326 (Text edit mishandles span of just colored spaces) 4. It incorporates further changes to text editing so that style can be changed on spans consisting of only spaces when text decorations are present in the span. 5. It incorporates code to disable text decorations when text so marked is mapped onto a path. 6. Fixed more bugs in Hebrew language support than I can remember. Hebrew language export/import to EMF now works quite well. (See the examples in libTERE v 0.7.) WMF does not support unicode and for all intents and purposes Inkscape has no way to read or write Hebrew to it. Some of more important things that now work that didn't (or didn't always): Hebrew diacritical marks, R/L/center justification, and bidirectional text. The Hebrew fonts "Ezra SIL" and "EZRA SIL SR" should be installed before viewing the libTERE examples, otherwise font substitutions will cause some text shifts. 7. Implemented font failover in Text Reassemble, which makes the process more robust. (Again, see the examples in libTERE. )

Fix for 871563 : JPG images are recompressed with lower quality when embedded

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

Merged Item.

Merged FlowX classes.

Checking file presence before calling lstat (should fix Bug #785701 Inkscape freezes at opening)

Registered classes with new factory. Hkern, Vkern and FeFuncX have to be rewritten, as they aren't real 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.

Various changes.

Clean up more GObject type definitions

Warning and dead code cleanup.

Fix for Bug #768149 (Incorrect Image URL can cause Loop) by Kris.

Added virtual pad to SPFlowtext; removed old calls to virtual SPItem methods.

code cleanup: add own includes to cpp files or make the functions static if they are not used elsewhere.

revert changes not strictly required for EMF support

Fixes bug #986271: memory leak with bitmap images

Added "virtual pad" to SPImage.

Fix for 367607 : Remove deprecated GTK+ symbols - Deprecated *_unref symbols replaced with g_object_unref

Warning and uninitialized variable cleanup.

Warning cleanup.

Remove NRRect use from the extension system

Refactor SPItem bounding box methods: remove NRRect usage and make code using them more obvious. Fix filter region computation.

Refactoring of the snapping preferences; mainly about storing all toggles in a single array, instead of each having its own member variable

Rewrite NRArena -> Inkscape::Drawing. Call render and update methods on the Drawing rather than on the root DrawingItem.

Rewrite NRArenaItem hierarchy into C++

- 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

Cleanup of oudated/redundant SP_ITEM() macro use.

Refactored to abstract lcms usage more. Added CMSSystem class.

Next step in refactoring color management. More to come.

Remove more of libnr

C++fied SPDocument added

Fix icons

Bitmap image rendering

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].

Fix typo

get rid of sp_repr_document wrapper function
