Rasdaman and libpng15

[Ernesto Rodriguez]

Rasdaman dosen't compie with version 15 of the png library.

error: invalid use of incomplete type ‘png_info {aka struct png_info_def}’

[Heinrich Stamerjohanns]

png15 does not allow direct access to info_ptr.

Just to remember what needs to be done:
(setjmp(read_ptr→jmpbuf)) needs to be replaced by (setjmp(png_jmpbuf(read_ptr)))

instead of accessing &(info_ptr→trans_vals.read)

something like this needs to be done:

png_color_16p trans_color;

if (png_get_tRNS(read_ptr, read_info_ptr, &trans_alpha, &num_trans,

&trans_color))

then continue with trans_color…

You might want to check with Dimitar whether this still needs a patch. encode() might replace the png() function there?

Yes I think it's not worth investing into this, let's close the ticket.
