Resolves: fdo#84729 buffer cache grows to over 9000 unused entries
regression from
commit a5351434fbea1126961f5dbaa986e7c9e686c24e

fix rendering issues in iOS with aqua
because now the cache just fills up because nothing will have
a depth of "0" and a new entry is created every time.
0 could be seen to mean "whatever is a good non-1bit depth" or auto or
something. (Do the uses of "8" really mean 8)
0 passed to new VirtualDevice under Linux/X ends up using the depth of the
outputdev, so here set nBits to that value to start with and the problem
goes away
