fmesher 0.1.7 (2024-07-01)

Fix regression bug in fm_manifold() that made it ignore all but the first given type options. See #16 (version `0.1.6.9001)
Fix plot.fm_mesh_2d vectorisation bug (version 0.1.6.9002)
Add new fm_subdivide() method for fm_mesh_2d meshes (version 0.1.6.9003)

Fix for hiding away-facing triangle edges in plot.fm_mesh_2d() and lines.fm_segm().
Fix duplicated fm_unify_coords.sf() method. Thanks to Pablo Paccioretti for debugging and reporting, see #13 (version 0.1.5.9001)
Use batched fm_bary.fm_mesh_2d() computations for data sizes of 2e5 and upwards. This improves performance of fm_basis()/inla.spde.make.A() for large data sets, see #14 (version 0.1.5.9002)
Automatically convert raw sfc samplers objects to sf objects in fm_int.list() (version 0.1.5.9003)
Detect and warn about unsupported use of fm_segm objects in fm_int.list() (version 0.1.5.9004)
Add fm_basis() and fm_fem() support for fm_tensor function spaces (version 0.1.5.9005)
Add fm_CRS() support for terra objects (version 0.1.5.9006)

Fix bug in fm_matern_sample() that prevented the use of a non-NULL loc argument. For earlier versions, the workaround is to make a separate call to fm_evaluate() after calling fm_matern_sample().
Improve speed of fm_block_log_shift() by an order of magnitude for multi-block cases.
Fix bug in plot.fm_mesh_2d for meshes with 2D coordinate storage (version 0.1.4.9002)

Fix bug in fm_rcdt_2d_inla() that gave different defaults for the extend and refine arguments when equal to TRUE, that should be treated the same as list() (version 0.1.2.9001)
Fix bug in fm_rcdt_2d_inla() to properly update n basis counter element when removing unused vertices. (version 0.1.2.9002)
Fix bug giving a spurious warning about inconsistent is.bnd for empty fm_segm objects, and inconsistent grp vector lengths. (version 0.1.2.9003)
Convert some of the old potentially unsafe C++ pointer methods to type safe C++17 features

Various documentation improvements, in particular for INLA compatibility
Modify mesh refinement tests to directly check the refinement criteria instead of the specific mesh result, to account for differences in floating point behaviour on M1 processors.
Modify tests of non-mesh-generation features to use precomputed meshes or meshes with stable properties
Protect against invalid tv inputs
Revert from \text{} to \textrm{}, as AMS extensions are only supported from R 4.2.2 (https://www.stats.bris.ac.uk/R/doc/manuals/r-devel/R-exts.pdf 2023-08-24, page 90), and CRAN oldrel for macOS is 4.2.0, not 4.2.3

Simplify LICENSE information in the R package DESCRIPTION
Fix example for legacy plot_PolySet method
Fix C++ unused-variable warning detected by clang-tidy version 16.0.6
Add workaround for sf::st_buffer not supporting negative distance for s2 with longlat coordinates. Fixes #5

Full conversion of the fmesher interface from the standalone binary in R-INLA (https://www.r-inla.org) to an interface powered by Rcpp (https://cran.r-project.org/package=Rcpp)
Tools for 2D and 1D function spaces, see fm_mesh_2d() and fm_mesh_1d()
Tools for CRS handling see fm_crs() and fm_transform()
Plotting support for base graphics, rgl, and ggplot2
Added basic GMRF tools, see fm_matern_precision()
