[QGIS-Developer] Processing plugin - Set style on resulting layer

[Alexander Bruy]

Processing allows to define styles for outpus on the per-algorithm basis.
Just open algorithm context menu by right-clicking on it and select "Edit
rendering styles for outputs". In the dialog you can assign styles for each
algorithm output. These styles will be applied to outputs automatically
after algorithm execution.

Hope this helps.
