Title: bgcolor=transparent does not work in gif output
Submitter: Emden R. Gansner
Date: Tue Jul 28 16:06:35 2009
Subsys: Output generation
Version: 2.25
System: *-*-
Severity: minor
Problem:
With -Tgif:gd, the background appears to be off-white; with -Tgif:cairo, the image is black.

(Make sure to use a viewer like ImageMagick or Preview that can handle transparent backgrounds.)
Input: 

graph G {
  bgcolor=transparent
  a -- b
}
Output file: b1729.gif
Comments:
[ellson] Cairo output is fixed. As for gif, it works better now, but antialising looks poor because there is no compositing against the final background.
