[QGIS-Developer] Custom symbology for vectors in QgsMeshLayer

[Saber Razmjooei]

Hi Brian,

This has been raised before for displaying NOAA data. It is not something
possible at the moment, but we would be definitely interested in extending
mesh symbology to support other styles apart from arrows and streamlines. I
think my colleague @Peter Petrik <peter.petrik at lutraconsulting.co.uk> had
looked into this briefly in the past.

Kind regards
Saber
