Move some code from filter primitives to cairo-utils.cpp. Fix bug in lighting primitives.

Add support for color-interpolation-filters = linearRGB.

Correct the formula of the displacement map so that zero alpha value means maximum negative displacement rather than zero displacement. Fixes artifacts in filters.

Update 2Geom. Remove all use of NRRectL.

Initial autocache work

Remove more of libnr

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.

Displacement map filter

Fix for bug #455302 and bug #165529, also partially fixes bounding box of various NR Arena Items as passed to filters (it used to explicitly make the bounding box larger) and makes nr-filter-displacement-map use rowstride

updating my email address in file headers

Swap iterations over x and y coordinate to be more cache friendly (so the inner loop iterates over x).

Reverts "fix" of offset in the displacement map code (and adds a comment to prevent another misunderstanding).

Fixed offset in interpolation in nr-filter-displacement-map

Fix a divide-by-zero problem apparently introduced in r21012.

Some extra comments.

And now gradients should be (almost) perfect... The gradient vector is set up to be a good approximation to the "true" gradient and it is used consistently throughout (I hope). Also some other, minor, tweaks and a small bugfix.

Some quality improvements to feDisplacementMap handling (as well as extra boundary checks where necessary).

Move filters into their own namespace Inkscape::Filters (from NR::)

get rid of a lot of no longer needed "libnr/nr-..." includes.

2geom more as fix

more 2geomification

No more NRMatrix or NRPoint.

pixblock-transform and scaler: convert src if needed, to match dest mode. color matrix, comp. transfert and diplacement map: explicitely free some unused pixblock instead of resting on garbage collection...

* convert to non-premultiplied alpha on fedisplacementmap * corrected a slight mistake on a comment (!) on fecolormatrix :-P

* use enums to deal with displacementmap channel selectors * set default values explicitly for all combobox filter settings at the filters dialog.

feDisplacementMap resolution independence fix sent by JF Barraud

Warning cleanup

Modified filter primitives' render method to use FilterUnits instead of Matrix

Added 'paraller axis' rendering hint to filter primitives, that need it.

* moved some parameter inits from nr-filter-displacement-map to sp-fedisplacementmap * fixed rederer bug on feDisplacementMap. (handling of input and output buffers with different sizes is a dificult task. We should find out a way of making it cleaner)

added helper methods NumberOptNumber::numIsSet() and NumberOptNumber::optNumIsSet() using it for default attribute values in feTubulence and feConvolvematrix feDisplacementMap scale parameter variable is a double

boiler plate code for feTurbulence: *reading attributes and setting default values same for some more attributes on convolve matrix filter alphabetical ordering on Makefile_insert and on nr-filter.cpp #includes

improving displacement map renderer.

DisplacementMap filter boilerplate code + renderer draft implementation. General setting of attributes and default values. renderer method is still not correct. Needs some more effort.
