[PATCH] Use an 8bpp virtual device (instead of a 1bpp one) in sw and...

Hi,

I have submitted a patch for review:

    https://gerrit.libreoffice.org/2979

To pull it, you can do:

    git pull ssh://gerrit.libreoffice.org:29418/core refs/changes/79/2979/1

Use an 8bpp virtual device (instead of a 1bpp one) in sw and sc

The reason why a 1bpp virtual device is used is unclear to me. Using an 8bpp
one instead doesn't seem to cause any harm, and in the iOS port a 1bpp virtual
device actually does cause complications.
