+*) 19 may 2025: Separated chunk decoding from image decoding and expansion.
+   A user can now first decode all the chunks to learn details of the image
+   then decompress and, possibly, convert the image data.
 *) 6 may 2025: renamed mDCv to mDCV and cLLi to cLLI as per the recent rename
    in the draft png third edition spec. Please note that while the third
    edition is not finalized, backwards-incompatible changes to its features are
