Reorganize FrameBorderPrimitive creation (II)
Step5: Move the view-dependent decomposition from
BorderLinePrimitive2D to SdrFrameBorderPrimitive2D.
It is now possible to use discrete sizes before the
line and edge matching is done what will look much
better. When it was done at BorderLinePrimitive2D
and the matching was already done, that match was
'displaced' with the adapted forced scale to discrete
units.
The space and size used when zooming out for a single
discrete unit (pixel) can heavily vary - it just covers
a much larger logical area than the 'real' line/poly
would do. All this needs to be handled (also for bound
ranges) and can only be in a good way using primitives.
Adapted to no longer do view-dependent changes in
BorderLinePrimitive2D. Adapted to do these now at
SdrFrameBorderPrimitive2D. Currently used to force
the existing border partial lines (up to three) to
not get taller than one logical unit.
Adapted to no longer switch off AntiAliased rendering
in VclPixelProcessor2D for processBorderLinePrimitive2D,
this is problematic with various renderers on various
systems (e.g. vcl still falls back to render multiple
one-pixel-lines when taller than 3.5 pixels which looks
horrible combined with other parts like filled polygons)
All this needs fine balancing on
- all systems
- all renderers
- all apps (which all have their own table implementation)
- all render targets (pixel/PDF/print/slideshow/...)
Done as thorough as possible, but may need additional
finetuning. May also be a motivation to move away from
vcl and implement these urgetly needed system-dependent
primitive renderers...
Adapted UnitTest testDoublePixelProcessing with the needed
comments.
