* [MESH] [FEATURE] Sets meh color ramp classification from metadata read by MDAL driver.
Some mesh layer formats can provide values that can be compressed by categorizing values in consecutive intervals, each represent by an integer or byte. MDAL has the capabilities to recognize this dataset type and store the bounds of each class an the units in the metadata.
QGIS uses this metadata to setup adapted color ramp shader.
* [MDAL] update to pre-release 0.5.92
* 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.
[FEATURE] [MESH] add new 3d stacked mesh averaging methods (top, bottom, sigma, depth, height, elevation)
see https://fvwiki.tuflow.com/index.php?title=Depth_Averaging_Results for description of the methods. method can be selected for 3d stacked mesh dataset in the new widget added for QGIS 3.12 in the mesh layer styling dialog
Similarly to raster calculator, mesh calculator can take dataset groups from current mesh layer and
combine them with various aritmentic/logical operators to new dataset group.
Introducting MDAL, QgsMeshLayer, mesh data providers (mesh_memory, mdal)
to read and visualize raw meshes: vertices and faces. Support dragging
2dm files from browser on canvas to visualize 2dm meshes.
Support for QgsMeshLayer in Python API.
