* MDAL 0.5.90 : support for custom Logger and 1D meshes * [FEATURE] [MESH] Support rendering of 1D meshes, see https://github.com/qgis/QGIS-Enhancement-Proposals/issues/164 1D mesh consist of edges (edge is straight line segment with 2 vertices) and the data that is defined on either vertices or edges. Such data can be loaded by MDAL and rendered as mesh layer in QGIS.
