Robert Osfield 8c4da68338 From Philip Lownman, "The libpng project decided to rename png_set_gray_1_2_4_to_8() to ... png_set_expand_gray_1_2_4_to_8() with the 1.2.9 release. This submission fixes builds of the OSG against versions of libpng < 1.2.9 that don't have the new symbol available. This affects platforms like Red Hat Enterprise Linux 4 which come with libpng 1.2.7."		2010-02-26 08:55:50 +00:00
