9b07075fae Add a switch to QgsTessellator to avoid z handling and fallback to a 
purely 2d tesselation

Optimises tessellation when only a 2d tessellation is required by
skipping unnecessary/unwanted calculations

b7062b54f6 More optimisations to tesselation conversion to tri polys 
Use an unordered set for previously encountered points, avoids expensive
loop through existing points to determine point uniqueness

efcc9c5240 Some optimisations for QgsTessellator::_check_intersecting_rings to avoid unecessary cloning and repeated geos conversions 2019-10-02 21:37:52 +10:00

04ca01a795 Because QgsTessellator ONLY works with QgsPolygon geometry inputs, 
we can safely assume all rings are QgsLineStrings (not the abstract
QgsCurve type) and accordingly can use optimised methods for retrieving
points from the rings

8ee1c20bb2 [tesselator] Allow internal scaling of coordinates by input coordinate

Do not assume PostGIS 2.0+ has raster (#32064) 
People installing PostGIS via scripts do not necessarely install
raster support, even after PostGIS 2.0.
Starting with PostGIS 3.0 the raster support is not enforced as
active even when installing via extension.

This change detects raster support by the presence of a "raster"
named custom type.

45e847ef69 [layouts][needs-docs] Move page background setting to a per-page option 
The UI for this setting was sitting under the page properties panel,
which led users to believe it was a per-page setting (rather than
applying to ALL pages in the layout).

Instead, move this property to sit within individual layout item pages
so that the behavior matches what the UI suggests.
