Inadvertent logic error in g_return_val_if_fail()
style sanity checks implemented in
gimp_drawable_get_color_at() gave rise to
segment violation reported in #6624;
error admitted out-of-bounds x&y that
do not map to tiles. Closes #6624.
GTK-critical warnings which result from
this new sanity check require that
gimp_drawable_get_color_at() clients
perform initial culling of out-of-bounds
x & y coordinates.
