 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).

                      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

-Bug 1610814 - Fix NEON compile error with gcc and RGB unpacking. r=lsalzman

-This patch makes us use the correct intrinsic for loading a uint8x16
-register. It is not entirely clear why clang accepts this without
-complaint but beyond the types, it should be equivalent.

 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
