-	Function: png_open
-
-	This function reads or writes a png from/to the specified callback. The callbacks should be of the format:
-
-	> size_t (*png_write_callback_t)(void* input, size_t size, size_t numel, void* user_pointer);
-	> size_t (*png_read_callback_t)(void* output, size_t size, size_t numel, void* user_pointer).
-
-	Only one callback has to be specified. The read callback in case of PNG reading, otherwise the write callback.
-
-	Writing:
-	The callback will be called like fwrite.
-
-	Reading:
-	The callback will be called each time pnglite needs more data. The callback should read as much data as requested, 
-	or return 0. This should always be possible if the PNG is sane.	If the output-buffer is a null-pointer the callback 
-	should only skip ahead the specified number of elements. If the callback is a null-pointer the user_pointer will be 
-	treated as a file pointer (use png_open_file instead).
-
-	Parameters:
-		png - png_t struct
-		read_fun - Callback function for reading.
-		user_pointer - User pointer to be passed to read_fun.
-
-	Returns:
-		PNG_NO_ERROR on success, otherwise an error code.
