for the png_set_gAMA(), png_set_cHRM(), and corresponding png_get_()
functions will be needed.
4. September 1999 -- BUG [FIXED] --
Portions of the new MMX code in pngvcrd.c were ifdef'd out because they
didn't work properly, but the bug appears to have been found and fixed.
As a result, all parts of the code are once again enabled. If you think
there's still a problem, you can recompile with one of the following two
macros defined and see if the problem goes away:
DISABLE_PNGVCRD_COMBINE
DISABLE_PNGVCRD_INTERLACE
The second one is in the function where the bug was; as far as we are
aware, there was never any bug in the other function. Please notify us
if you find any problems in libpng, regardless of whether the two macros
make any difference: png-implement@ccrc.wustl.edu
Again, we believe the MMX code in pngvcrd.c is 100% correct, but it has
not yet been tested extensively.
