This implements the recent functionality extension of painting
cosmetic (untransformed) brush patterns, and the corresponding
NonCosmeticBrushPatterns render hint, in the pdf and opengl paint
engines.
As part of the implementation it also fixes a couple of pre-existing
bugs in the opengl engine, relating to updating the brush after
changes in transformation or brush origin.
As a driveby, it also includes a minor fix for the lance testing tool:
request stencil buffer, as that is needed and not always provided by
default. This echoes a recent fix done to tst_baseline_painting.

[ChangeLog][QtGui][QPainter] In Qt 5, the predefined brush patterns
would always be transformed along with the object being painted. In Qt
6.0 onwards, they would or would not, depending on the
SmoothPixmapTransformation render hint. Instead of this somewhat
surprising behavior, make the default be untransformed
(i.e. cosmetic), which makes sense when it comes to dpr scaling. For
the cases where one wants scaling, a new render hint is introduced to
enable that: NonCosmeticPatternBrushes.
