tdf#159626 vml pattern import: add color, fix back/foreground
This depends on tdf#126533 which imports page style v:fill,
BUT ONLY IN ORDER TO support the unit tests.
The patch itself can stand alone
and fixes vml import into textboxes/shapes etc.
i.e. backporting could be possible by dropping the unit tests.
The pattern that VML uses to indicate foreground
and background is very different from what LO needs.
[Fortunately LO does not use the _guess_ from
vcl::bitmap::isHistorical8x8 to determine which
color is the background. Instead it always uses the first pixel.]
Documentation says that unspecified XML_fillcolor
and XML_color should be white, but observation
says it should be 25% gray (Word 2003).
25% gray == C0C0C0 == fillcolor="silver" == COL_LIGHTGRAY
Currently, we simply export as a colored, tiled image,
and not as a B&W type="pattern"
so no corresponding export changes need to be made to export.
Existing unit test documents that are affected:
-chart2export's PieChartDataLabels.docx (page background)
-ooxmlexport5's fdo77725.docx (minimized PieChartDataLabels.docx)
* both foreground and background are set to white => solid white
-sw/qa/core/data/ooxml/pass/fdo79131.docx (shape "inline")
