	A first version of a perspective LPE has been in SVN for a while now, although it still lacks a lot of interactivity. This will be improved after this year's Summer of Code when LPEs will be a lot better integrated (e.g., when handle management is added).

			====Bevel====
			Adds a bevel to an object. Some of the options could be:
			* Bevel extension.
			* Bevel height. The height is simulated with the luminosity of the sides of the bevel.
			* Sharpness, i. e.: how rounded/hard should the corners be.
			* Direction of light (in degrees).
			* Distance from the light to the object.
			* Color of the light.
			* Shape of the bevel.
			* Any other? Add it here.

			The bevel should be simulated with multiples facets, each one having a varying shade of light according to light parameters and the object's own color. The extension and light position should be editable on canvas.
			I will try to do a full fledged blueprint on the following days.

This second example is about lpe output: alowing full svg data would widely enlarge the range of possibilities, for instance deforming colorfull objects (notice this already possible using [http://wiki.inkscape.org/wiki/index.php/LPE_for_groups lpe on groups]!!), or interpolate between styles at the same time as shapes.
