* Major dmnsn_kD_splay_search() optimization.Tavian Barnes2009-10-261-19/+21
| | | | | | | | At each level of recursion, we have to go down the right branch if it exists. But if we do this before we test the current node and the left branch, we can eliminate those tests in the likely case that we find a closer object in the geometrically larger right subtree. This gives about a 2X speed improvement according to `make bench'.
* Clean up some dmnsn_new_*() functions.Tavian Barnes2009-10-264-64/+37
| | | | | Rather than special-case every failed memory allocation, just make dmnsn_delete_*() more robust and call it.
* Delete empty cube.c.Tavian Barnes2009-10-261-23/+0
|
* Call dmnsn_done_progress() later in dmnsn_finish_progress().Tavian Barnes2009-10-261-3/+2
|
* Don't check if it's too late to add canvas optimizers.Tavian Barnes2009-10-264-26/+6
| | | | This fixes some errors displayed by concurrency checkers like helgrind and drd.

* Fix make distcheck.Tavian Barnes2009-10-252-4/+9
| | | | | Tests and benchmarks were using $(top_srcdir) instead of $(top_builddir) to refer to libraries, and PNG files were not being cleaned.
