Bartosz Kosiorek 3a9027609e tdf#53004 tdf#142495 WMF EMF Fix displaying Text with OPAQUE and CLIPPED 
With OPAQUE option enabled, the rectangle need to be drawn,
before drawing text.

With CLIPPED option enabled, the text needs to be drawn
only inside rectangle.

In previous implementation, the rectangle read was skipped and
it was not drawn (for OPAQUE).

For CLIPPED the rectangle was read but Clip was not applied
to text drawing

This commit fix that issues, and allow to draw rectangle correctly,
with BGColor (background color), and add support for Text Clipping
according to [MS-WMF] and [MS-EMF] specification.
The fix applied to EMR_EXTTEXTOUTW, EMR_EXTTEXTOUTA and EXTTEXTOUT records
