ALG: It is converted to a 28x28 pixel bitmap, probably because it needs to be a
fill style for page background. The method used is lclDrawHatch. It may be
possible to change this to creation of a bitmap for the whole page, but this
would extend the export size unnecessarily.

ALG: Found a way to use a MetaFile when exporting a hatch filled background
instead of a limited bitmap. This works well and ppt will use and show vector
data. This also solves the size and quality problem.
Only caveat is that the roundtrip shows bad quality. After investigation it
shows that this is just a visualisation problem; as a result of #119125# any
graphic can be used as fill style, but it's usage in SdrFillBitmapAttribute
will still always convert it to a BitmapEx. This is a very good target for a
further change to keep evtl. metafile and/or svg data down to the primitive
usages. Taking a deeper look...

ALG: The change to use vector data in the pipeline is a bigger change, wrote
#121194# for it. This task is done.

--- Comment #5 from Armin Le Grand <Ar...@me.com> ---
ALG: First step: Buffer evtl. created Bitmap/BitmapEx in ImpGraphic in the
local BitmapEx (maEx) when Graphic is a metafile. This is similar to buffering
SVG's replacement graphic and pretty straight forward, should workl the same as
with svg and avoid multiple renderings.
