textures
now. Implementation is almost complete beside of the not yet done Qt
antialiasing mode. Not all sort of linear gradients ( see
QLinearGradients ) are implemented - needs 1-2 days more.
The aspect flags for box primitives have been substantially changed
from
too atomic to more strutured units.
The skins are currently incomplete - will be fixed later.
