IMAGE: Remove unnecessary check from Image::writePNG() 
Surfaces with pixel formats not supported by libpng are already converted to RGBA, meaning that the check isn't needed.

8a8ac63636 IMAGE: Add a paletted transparency mode flag to PNGDecoder 
Previously, the PNGDecoder would always convert images that
have a palette with a transparent color(s) to a full RGBA
surface automatically. There needed to be a way to diable
this and keep the image paletted for the Glk engine, since
some Infocom V6 game Blorb files reuse the palettes from
previous images, so I couldn't have the decoder using the
dummy palette that comes with the image

194984de2f IMAGE: Remove unused end info structs from PNG code 
Thanks to @dafioram for noticing the problem & sending an initial
patch, and to @wjp for noticing further that the PNG reader did not
even use the end info struct it created either.

Fixes Trac#10217. Closes gh-1028.
