  1. Icons: Make PNG/XPM transparent, hi-res 

    Extend the ImageMagick `convert` commands for generating icon bitmaps:
- Add `-background none`, to render with background transparency.
- Add `-density 300x300`, to render larger sizes at full resolution.

Because the SVG's internal coordinate system is only sized for
64x64 pixels, ImageMagick will render at that size and then scale
the _bitmap_ up, when outputting larger image sizes. Increasing
the DPI using `-density` allows it to upscale the SVG vectors at
full resolution.

  2. Reset icon DPI to 96x96 (screen-res) 

    Output the icon bitmap images at standard 96 DPI, not the 300 DPI we
temporarily scaled the coordinate system to when rasterizing the SVG.
