Perspective Transformation

[Aurium]

The SVG Transforms Requirements from February 2009 (http://dev.w3.org/SVG/modules/transforms/SVGTransformsReqs.html) says: SVG Transforms must support perspective transformations.

Ok, we know and we want! :-)

The perspective specification draft is here: http://www.w3.org/TR/SVG-Transforms/#perspective-property

I think the Inkscape must implement this support sooner then possible to allow good perspective usage and perspective to bitmaps. While W3C do not end the specification, Inkscape may use a inkscape namespace like mozilla and webkit does to CSS.

We must add a failback to perspective transformation?
The failback will not be cool for groups. We will double all the code. To the bitmaps we will need to remake the image to register the perspective, so the final SVG will have 2 bitmaps for each transformed.

On "Inkscape SVG" i propose to not register a failback, but on "Plain SVG" we may (before save) replace the perspective transformations by currently valid SVG elements: converted paths and bitmaps. Optionally we may have a button "apply transformation" to convert the perspective transformations on selected element into currently valid SVG elements.
