/** VclMetafileProcessor2D class
|
|
|
|
This processor derived from VclProcessor2D is the base class for rendering
|
|
all feeded primitives to a classical VCL-Metafile, including all over the
|
|
time grown extra data in comments and PDF exception data creations. Also
|
|
printing needs some exception stuff.
|
|
|
|
All in all it is needed to emulate the old ::paint output from the old
|
|
Drawinglayer as long as exporters and/or filters still use the Metafile
|
|
and the extra-data added to it (which can be seen mostly as 'extensions'
|
|
or simply as 'hacks').
