Similir to the work in patch 11468 (platform/graphics addition), KCanvasFilters has to be reworked. It contains dozens of classes, cluttered in one file - same for KCanvasFilterQuartz.h/mm.
My proposal is: (already discussed with Oliver)
Add new directory platform/graphics/svg/filters, and filters/cg.
Split up KCanvasFilters in quite some new classes, and move them to platform/graphics/svg/filters.
Move the SVGResourceFilter class to platform/graphics/svg, similar to masker/clipper resources.
Add the cg implementations of the filter effects in platform/graphics/svg/filters/cg, named
SVGFETileCg.mm, SVGFEBlendCg.mm etc.
Move KCanvasPoint3F from kcanvas/device/KCanvasFilters.cpp/h to platform/graphics/FloatPoint3D.
Move everything from kcanvas/device/quartz/filters/* to platform/graphics/svg/filters/cg/.
(These are the cikernel files, all named Wk*Filter)
All these togeter kill KCanvasFilters.cpp/h and KCanvasFiltersQuartz.cpp/h, this is the last
file in the kcanvas/ directory, it's empty now. kcanvas/device is the next victim...
Attaching patch soon
Created attachment 11520 [details]
Large patch including ChangeLogs.
The commiter must move the Wk* files from kcanvas/device/quartz/filters to platform/graphics/svg/filters/cg (svn move!) this can't be included in the patch, it would add/remove these files and loose history.
Finally the duplicated SVGFilter* enums are gone, and shared between platform/graphics/svg/filters
and ksvg2/svg. All build system changes for Qt & Mac are included.
Have fun reviewing! :-)
Do these really belong in the platform directory? I'm concerned that more and more of the SVG implementation is being moved into the platform directory.
that totally depends on how the WebKit structure should be in future.
For me platform/ means, platform specific implementations go there,
and for instance svg filters have to be implemented for every platform.
We could also have ksvg2/filters of course, with ksvg2/filters/cg,
ksvg2/filters/qt subdirectories. My personal opinion would be to
go with platform/graphics/svg for platform specific svg code.
If you have any worries with that, please elaborate :-)
Holding back commit for now, to give Darin a chance to comment.
Would be nice if you could manage to reply today (Friday), as I only
got hacking time today/tonite :-)
Thanks in advance,

That's not quite right.
We expect to have platform-specific implementations in some other places in the source tree, here and there. What goes into the platform directory is a platform abstraction that the rest of the code is built on. But in some cases, you can't build the platform specifics into a platform abstraction -- you need platform specifics in the actual high level code.
At the moment, the directories that are doing this are page and loader. (Much of the code currently in bridge/mac belongs in page/mac.) While we'd like to keep from doing this all over the code, we will need platform specifics outside the platform directory when they can't easily be abstracted into a generic cross-platform concept.
If we came up with a way to make filters a concept that was independent of SVG, then I think platform/graphics/filters would be a fine location.
But as long as the filter implementation is closely tied to the SVG implementation, even if it has platform-specific pieces, it should be in svg/filters, with svg/filters/ci or cg and other such subdirectories as needed to keep the platform-specific parts in their own subdirectories.

I do have worries about that. This is not the original concept that Hyatt created about what the platform directory is.
I see signs that people are misunderstanding this. For example, FrameQt and PageQt absolutely do not belong in platform/qt. They should be in page/qt instead.
I'm sorry that this wasn't explained clearly enough in the past; we probably need to write more about it. I don't mean to make your work more difficult. Please talk to Hyatt and Maciej about this too as the three of us worked together on this design and strategy. I want others in the project to make comments about it too and help us get it just right.
fair enough, this is the first real explaination about platform/
that I've read - and I like it and agree with it.
Compromise: Can I commit this patch as-is, and move the _whole_
platform/graphics/svg directory into ksvg2 subdirectory?
With your explaination about platform/, the platform/graphics directory
makes a lot of sense, but platform/graphics/svg not.
You're okay with this?

Sounds fine to me. What I care about most is the end point, not the path to get there.
