commit f21f0f0ff656880149cfdfd34b8984c9541bca24
Author: Miklos Vajna <vmik...@collabora.com>

VML import: handle <v:imagedata gain="..." blacklevel="...">
Map it to (the UNO API of) GraphicDrawMode::Watermark, similar to what
the binary import does in SvxMSDffManager::ImportGraphic() and how the
drawingML import does it in
oox::drawingml::GraphicProperties::pushToPropMap().
On export, the drawingML export is used, and that already maps
GraphicDrawMode::Watermark to <a:lum bright="70000" contrast="-70000">.
(cherry picked from commit 90556b6df0f6378fb60d7dee18b2f5d275ece530)
