png_info has no member by the name trans

If you get the error

png_info has no member called trans

while compiling directfb the following workaround might help

The name of the values "trans" and the "trans_values" has changed in the structure png_info defined in png.h

Open the file that is generating the error and change the values of

trans to trans_alpha
trans_values to trans_color

this should take care of the errors.
