Hi Martin,
Thank you for your work on removing the old symbology stuff.
Marco is working on data-defined symbology and it is already in master.
These are now all on the symbol level as you may want different
rotations for each component of a combined symbol. Also the units are
now more fine-grained. As an exaple you can define a size in map units
and the outline in mm.
I agree that the texture for fill style is obsolete as we have the line
and point pattern editors and SVG patterns.

Hi
just a quick note that old symbology API has been removed:
QgsRenderer
(+ implementations), QgsSymbol and few others are gone. Projects
using
old symbology still can be loaded and old symbology will be
automatically converted to new symbology (just in memory, so if you
do
not save the project it will continue using old symbology). There are
few things that are currently not being converted properly to new
symbology:
- data-defined rotation / scale / symbol name - TODO
- map units flag for point symbol - TODO
- texture for fill style - no equivalent in new symbology (svg fill
is
better anyway)
- continuous color renderer - no equivalent in new symbology
(graduated symbol renderer may be used instead)
- composer - legend items for old symbology are ignored and need to
be
recreated manually
Old labeling has been kept as-is - there's not so much code involved
(basically just one class, QgsLabel) so it's not such hot topic
within
the API cleanup.
I am aware that few unit tests related to rendering got broken, I
will
fix them soon. (btw. there are few failing tests not related to the
symbology changes: qgis_atlascompositiontest, qgis_composerhtmltest)
How do others feel about dropping "V2" postfix from new symbology
classes for QGIS 2.0? E.g. QgsSymbol instead of QgsSymbolV2. I would
like to see those removed to keep the API clean.
Regards
Martin
