c71b68ac45 build.gradle: fix arm64 build 
only armv7-a uses .c.neon, arm64 has NEON by default; this matches the
Android.mk

8e42ba4c80 simplify WEBP_EXTERN macro 
including the type in the macro doesn't bring much benefit to ordering,
current platforms work with a prefix, this would be insufficient if the
attribute needed to follow the function prototype. this form makes it
easier to override on the command line.

6878d42720 fix memory leak in SDL_Init() 
we use a static guard to only call SDL_Init() once.

Another option would be to call SDL_Quit(), but it doesn't seem to be
doing anything.

Also, fix the HTML code and add 'use strict' directive.

471c5755fc cmake: fix gif lib detection when cross compiling 
GIF find_package only locates the header and library, it doesn't fail
compile tests when detecting the version, but falls back to 3 (as of at
least cmake 3.7.2). Make sure the library links to avoid incorrect
detection when cross compiling.

7d67a1646d Lossy encoding: smoothen transparent areas to improve compression 
If "exact" is false, we can modify the luma samples in fully transparent
areas to facilitate lossy compression. Experiments on some PNG images
show compression improvement of more than 20%.

f209a5481e Use the plane code and not the distance when computing statistics. 
As backward references use the plane code when checking the cost
of a distance, statistics used to compute the cost should use it too.
This provides a small compression improvement at no speed cost.
