Matt Ebb d3028ec70d * Shrink/Fatten for bevelled curves 
This is a much faster and easier way to give a bevelled curve a taper, without
using taper curves. Each point on a curve now has a 'radius' value that you can
shrink and fatten using Alt S, which will influence the taper when the curve is
bevelled (either with a bevob, or with front/back turned off and a bevel dept
set). Alt S shrinks and fattens the selected points in an interactive transform,
and you can set an absolute radius for selected points with 'Set Radius' in the
curve specials menu.

See demo: http://mke3.net/blender/etc/curve_shrinkfatten-h264.mov

This can be a quick way to create revolved surfaces (eg.
http://mke3.net/blender/etc/wineglass-h264.mov ) and it would be very
interesting to use this radius value in other tools, such as a 'freehand curve'
tool that would let you draw a curve freehand, with the radius affected by pen
pressure, or even using the radius at each point to control curve guides for
particles more precisely, rather than the continous maxdist.
