tile_index() gains a tile argument, to evaluate the index at chosen
tile indices rather than materializing every row. tile_index(x, tile = i)
is identical to tile_index(x)[i, ], and i may be unordered or repeated.
The default tile = NULL is unchanged.
tile_index() now marks dangle tiles by their tile column and row rather
than by looking up global tile cell numbers, which is what allows an
arbitrary tile selection. Output for the full index is unchanged.
vaster::cell_from_col() and vaster::cell_from_row() are no longer used.
tile_index() gains a clip argument. The default TRUE is the existing
behaviour, clipping edge tiles to the pixels that exist. clip = FALSE
reports every tile at the full block size, with the edge tiles extending
past the grid - which is what a block of a tiled format occupies on disk,
and what a byte range covering that block has to describe.
new tiles_from_extent() solves for the tile indices a region overlaps,
from the tile grid rather than by testing tiles, so the cost does not grow
with the size of the scheme. Intended to feed tile_index(x, tile = ).
Tiles are half open, regions are clamped to the scheme, and a region that
misses entirely gives integer(0).
grout() is now the definitive user constructor; removed internal
.groutfrom() wrapper and dead dimXY compatibility branch.
.tilescheme() simplified: tile counts now computed with ceiling()
for clarity; removed duplicate "hack" comment logic.
print.grout_tiles() output uses x format for dimensions and now
returns x invisibly (not NULL).
plot.grout_tiles() rewritten to iterate individual tile rectangles
rather than relying on an unexported as_rect S3 method.
as_rect_grout() is now an internal helper (not an S3 generic);
.p2s() (unused) removed.
extent.grout_tilescheme() replaced by internal .tilescheme_extent().
tile_spec() and tile_zoom() cleaned up: explicit as.integer()
coercions, removed Remotes: dependency on dev vaster, informational
messages improved.
Comprehensive test suite added covering dangle trimming, contiguous
offsets, input validation, and tile_spec()/tile_zoom() output.
DESCRIPTION bumped to R (>= 3.5.0), added Config/testthat/edition: 3,
removed Remotes: field, added wk to Suggests.
New function tile_spec() to generate tile specification from input
extent and dimension at a given zoom. New function tile_zoom() returns
the natural maximum zoom value.
Removed all spatial input coercions; just use dimension + extent.
Added extent columns to tile_index().
Removed raster dependency; uses vaster for basic grid/cell logic.
