This commit adds a new avoid intersection mode setting when
digitizing new features. The three available modes are:
- allow intersections/overlaps
- avoid intersections/overlaps on active layer
- avoid intersectonss/overlaps on layers list
The third mode is what QGIS has had for a while, except
its UI/UX is a bit messy. The layers list is setup by
the user via the advanced snapping configuration widgets,
but isn't connected at all with whether snapping is
enabled / disabled.
This new approach makes it explicit to user whether
newly-added features might be clipped or not, and
if so by which layer(s).
Finally, the new 'avoid intersections/overlaps on
active layer' is likely a far more useful behavior
than having a list of layers (for e.g., you might
be digitizing on a layer that can't have overlap
with itself but is fine to overlap with another
layer, the latter also in need of avoid overlap
_with itself_).
The Random points on lines algorithm supplements the existing "Random points along line" algorithm, and will prove to be more useful to the majority of users than the "original".
Features:
The points are distributed randomly over the lines based on "along the line" distance, meaning that the distribution of the points will be flat over the length of the line (each place on the feature has the same probability of being "hit").
The Random points along line, on the other hand, uses a line segment based approach, meaning that the density will depend on the segment length (short segments will have a higher point density than longer ones).
This tool, which is available from the new F12 "dev tools" panel,
is a native port of @rduivenvoorde's network logger plugin.
It shows a list of ongoing and completed network requests, along
with a whole load of useful detail like request and reply status,
headers, errors, SSL configuration errors, timeouts, cache status,
etc.
Also has loads of polish and useful capabilities, such as the ability
to filter requests by URL substrings and status, and you can right-click
requests to open the URL in a browser or copy them as a cURL command.
Only minimal shells of objects are left in Python now, the bare minimum
required because they call objects which depend on Python compatibility
for deprecated API calls...
[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
Stacked 3D meshes store values on the volumes that are regularly stacked over base 2d mesh. User can select various 3d to 2d averaging/interpolation method to convert values on volumes (3d) to values on faces (2d) that can be shown in mesh layer. This is achieved by new tab in the mesh layer properties dialog.
* [FEATURE] Selective masking
Advanced rendering feature that allows the definition of 'masks' areas around labels or with a new typ of symbol layer. These masks will "un-draw" symbol layers of other layers underneath.
It modifies the rendering process by adding an optional second pass.
