version 1.4.6beta03 [January 14, 2011]
Fixed some typecasts in png_debug statements (Cosmin).

version 1.4.6beta04 [January 22, 2011]
Updated documentation of png_set|get_tRNS() (Thomas Klausner).
Added const_png_structp and const_png_infop types, and used them in
prototypes for most png_get_*() functions.
In the manual, describe the png_get_IHDR() arguments in the correct order.
Ported change in png_do_rgb_to_gray() from libpng-1.5.1, to make
it more robust against internal libpng coding errors.
