 Skia does not support big endian. The places to fix are too numerous and upstream (skia, not Mozilla)
 has no interest in maintaining big endian.
 So here we try to swizzle the input for skia, so that skia always works on LE, and when it comes
 out again, we transform back to BE.

 For FF68, AntiAliasing of XULTexts seem to be broken on big endian (s390x). Text and icons of the sandwich-menu to the
 right of the address bar, as well as plugin-windows appears transparant, which usually means unreadable (white on white).

 Problem description: Tab-titles that are too long to fit into a tab get faded out.
                     On big endian this is broken and instead of fading out, the 
                     tab gets white and the font transparent, leading to an unreadable
                     tab-title
 Solution: This is not a real solution, but a hack. The real solution would have been
          to byte-swap the correct buffer, but I could not find it.
          So the next best thing is to deactivate the fading-effect. Now all tab-titles
          are readable, albeit not as pretty to look at as they could be. 
 Side-effects: I have not yet found an unwanted side-effect.

 Problem:  webGL sites are displayed in the wrong color (usually blue-ish)
 Solution: Problem is with skia once again. Output of webgl seems endian-correct, but skia only
          knows how to deal with little endian.
          So we swizzle the output of webgl after reading it from readpixels()
 Note:     This does not fix all webGL sites, but is a step in the right direction

 commit 0b91f8a668201fc58fa732b8acc496caedfdbae0
 Author: Florian Weimer <fw@deneb.enyo.de>
 Date:   Sun Apr 29 12:18:33 2018 -0700
    Indicate that _PyGC_Head is only 8-byte aligned. (closes bpo-33374)
    By spec, the "long double" in _PyGC_Head requires the union to always be 16-byte
    aligned. However, obmalloc only yields 8-byte alignment. Compilers including GCC
    8 are starting to use alignment information to do store-merging. So, the "long
    double" needs to be changed to a simple "double" as was long ago done in Python
    3 by e348c8d154cf6342c79d627ebfe89dfe9de23817. For 2.7, we need to add some
    dummy padding to make sure _PyGC_Head stays the same size.
