[plt-scheme] Re: Drscheme icon

This has got to be the last revision or my advisor will kill me and 
dance about on my grave singing "Hallelujah!" The icons are here:

Per Eli's suggestions (which seem to be a good middle ground), I've made 
four versions of the red/blue with the traditional lambda. In order of 
decreasing bling, they are:

     plt-logo-red-shiny.svg
     plt-logo-red-diffuse.svg
     plt-logo-red-gradient.svg
     plt-logo-red-flat.svg

At least one of these should satisfy anyone from the iPhone generation 
all the way back to the Upper Paleolithic. (Though I'm certain 
Cro-Magnon would prefer the shiny one.)

The zip file also includes 256x256 renders in PNG format for computers 
that choke on rendering SVGs with blur, like my laptop.

Please redirect all further suggestions to your favorite vector graphics 
editor. :)
