97a4573885 [devel] Describe new filter-selection test in CHANGES and ANNOUNCE. 2009-07-19 15:10:36 -05:00
Glenn Randers-Pehrson
4ace0e1530 [devel] Revised the new test 
to run faster in the usual PNG_ALL_FILTERS case.  The previous, more
accurate test, would save some computation in uncommon cases, but is
probably not worth while in the long run.

9c90d7f4ee [devel] Revised test for avoiding filter selection tests 
to obtain the same result as previously when the user asks for
    a filter selection that does not include NONE or SUB, e.g., if
    the user asks for PAETH-only that's what they should get.

ae4af5600d [devel] Avoid some tests while selecting a filter. 
The AVG and PAETH filters will never be selected for the first
row, so we need not test them.

33188acf8f Eliminated PNG_LEGACY_SUPPORTED 
It is not of any use in libpng-1.4.0; it was only to support binary
compatibility between some old libpng-1.0.x versions.  It should have
been removed from libpng-1.2.x as well but it is too late for that now.
