[Qgis-developer] Old symbology removed in master

[Andreas Neumann]

 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 I agree that the texture for fill style is obsolete as we have the line 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.

 Andreas
