Currently SvtOptionsDrawinglayer::IsAntiAliasing() is used
in the constructor of the VCL based processor2Ds to decide
if AA is to be used or not. Using this inside the
constructors makes it currently impossible to use a
primitive renderer independent from these settings,
except when changing these settings temporarily what
may influence other renderings and is a hack.
The setting SvtOptionsDrawinglayer::IsAntiAliasing() is
intended to decide if LO shall use AA mode from user's
perspective, this means for the EditViews of the Apps
and some other occasions (previews, exports, conversions
to bitmap, ...).
This works currently since all visualizations for these
purposes use newly constructed primitive renderers. But
there is no way to use primitive renderers independent
from that setting. For future renderers which might be
used for other purposes this is not sufficient, there
has to be a method to create a renderer using e.g. AA
independent of the global setting.
To allow that, move the deciding flag to the already
used geometry::ViewInformation2D. To not change anything
initially, use the global flag for now to init that
default value at ViewInformation2D.
I took the opportunity to adapt ViewInformation2D to
no longer being read-only and not changeable, it uses
internally an impl class based on cow_wrapper already
anyways. Extending this would lead to the constructors
getting even bigger, when usually only 1-3 values
need to be changed and many usages want to copy an
existing instance and modify it. Adapted that usages
to a much smaller footprint.
Up to this point this does not change anything, but
move the usage of the SvtOptionsDrawinglayer to the
defaults (constructors) of the involved class
ViewInformation2D. Using this then in the primitive
rederers should be safe and will allow to use a
primitive renderer with or without AntiAliasing
independent of the user setting, so also for non-
EditView usages.
Also already added the PixelSnapHairline setting, this
will also be needed independent of user settings to
have full freedom of usage.
Unfortunately I cannot use SvtOptionsDrawinglayer
methods
::IsAntiAliasing() or
::IsSnapHorVerLinesToDiscrete
inside ViewInformation2D where I would need it. It's
now in drawinglayercore and thus not linked against
svtools (svt) anymore.
Thus I have to do some forwarding mechanisms to get
the correct values available in ViewInformation2D.
Not nice, caused by creating drawinglayercore...
