annotate ext/libpng-1.2.29/pngtrans.c @ 502:96c4922c1c24

Added some imports to the world initialization code. I had to do this because you were not able to use the editor with the shooter demo map files without manually adding the imports to the map file. You do not have to do this now (note the TODO in the comments). I have also hard coded the camera zoom level to ensure the map editors zoom level at the time of saving the map is not used.
