Allow edge resistance at both sides of a window and also when
edges don't overlap but are a single pixel away from doing so.
Fixes one of the zillions of issues covered in #321905.
* src/boxes.[ch]:
(meta_rectangle_edges_align):
new function to handle the overlap or off by one determining
whether edge resistance should kick in for an edge.
(meta_rectangle_edge_cmp_ignore_type):
new function to sort edges but ignore the type so that e.g. left &
right edges of windows can be used interchangeably.
(meta_rectangle_edge_cmp):
now uses meta_rectangle_edge_cmp_ignore_type() to do most the work
and just adds an extra condition
* src/edge-resistance.c:
(find_nearest_position):
use meta_rectangle_edges_align() now to determine whether the
edges align,
(apply_edge_resistance, apply_edge_resistance_to_each_side):
have the edge resistance kick in if either the beginning or ending
positions would cause overlap in the given direction -- fixes an
uncommon but annoying corner case,
(apply_edge_snapping, apply_edge_resistance_to_each_side,
meta_display_cleanup_edges,
stupid_sort_requiring_extra_pointer_dereference, cache_edges):
mix edges from both sides now
