read a PNG, the result will be in the same color type as the PNG (hence "generic")*/

Deflate for a block of type "dynamic", that is, with freely, optimally, created huffman trees*/

updates values of mode with a potentially smaller color model. mode_out should contain the user chosen color model, but will be overwritten with the n

palette must have 4 * palettesize bytes allocated, and given in format RGBARGBARGBARGBA... returns 0 if the palette is opaque, returns 1 if the palett

get the tree of a deflated block with dynamic tree, the tree itself is also Huffman compressed with a known tree*/
