I don't know if it's related, but in b3 nothing I do will allow me to
produce an image with BOTH OF .niceText = 1 AND .transparentBackground
= 1, UNLESS gdlib_png is set in the install tool. Also, simply adding
'format = png' to a gifbuilder object does NOT cause it to create a
png UNLESS gdlib_png is set in the install tool.

Have I misunderstood what your changes have made available (i.e. I
thought we could now swittch between gif/png/jpg in gifbuilder
objects...)?
