I was assured that those ifdefs are needed only when

http://cgit.freedesktop.org/libreoffice/core/commit/?id=0c9e4d9b223a0593686bee800484de3c23095d4f

is in place; and I did not backport that one.  So does it kick in even
if this is not there?

Well - no idea what is best there; either the bitmaps are extremely
small, but not scaled, or they have reasonable size, but every pixel
becomes a square...

I for myself am OK to live with the scaled bitmaps before we have an
icon set that either has bigger png's, or directly svg's, but that is I
guess to decide between people who actually have hi-dpi displays :-)

Having said that - why ifdef? ;-)  Why just not a function that does (or
does not) scale according to the DPI scale level & if it is / is not
OSX?

All the best,
