New description:
Currently, all viewers default to `$SAGE_BROWSER` if it is set, `$BROWSER`
or some other system-specific defaults (like `xdg-open`, if present)
otherwise.
The original proposal on this ticket was to support environment variables
for what is currently
* `sage.misc.viewer.DVI_VIEWER`,
* `sage.misc.viewer.PDF_VIEWER`, and
* `sage.misc.viewer.PNG_VIEWER`.
I think instead that if the user wants to change the defaults, then that
should happen in their init.sage file. The current patch allows them to
add lines like these:
{{{
from sage.misc.viewer import viewer
viewer.browser('open -a /Applications/Chrome.app')
viewer.png_viewer('display')
viewer.pdf_viewer('acroread')
viewer.dvi_viewer('/usr/bin/xdvi')
}}}
(or of course to use these interactively from the command line) and then
the appropriate program will be used.
