This updates the PNG library to 1.2.37, which fixes some bugs internal to the PNG library, and it turns on some functionality that O3D needs for manipulating PNG files: It removes the definition of PNG_NO_WRITE_FILLER, PNG_NO_READ_FILLER, PNG_NO_SEQUENTIAL_READ_SUPPORTED, and PNG_NO_INFO_IMAGE from pngusr.h so that the functions used by O3D to read images progressively and for filler bytes for pixel expansion (RGB -> RGBX) are available.
BUG=none
TEST=successful trybot run for all platforms.
