CVS version: Black background default for PNG

[Philipp K. J. <ja...@ie...>]

The current CVS version seems to make black the 
default background color for the PNG terminal. This
seems to be new behavior - the default used to be
white.

This seems to occur only for PNG, but not for the GIF
or JPG terminals.

I am not sure when this first occurred - the current 
CVS version behaves the way as just described, but
the did not do so a few months ago.

I think it would be desirable to have white again be the
background for the PNG terminal (consistent with the
other terminals).

Best,
