Now that the patches on which this bug depends are already in trunk, this patch should get applied without any conflicts.

Compilation options to choose AC method to use

I think that TEXTURE_MAPPER_CLUTTER might be a misleading name because the Clutter implementation of AC doesn't use TextureMapper.

Looks good, just some suggestions.

> Source/WebCore/GNUmakefile.am:568
> +if !USE_AC_CLUTTER

I've rather used the positive condition in this case, I think it is safer, actually you can probably remove the previous if and just check if USE_AC_TEXTURE_MAPPER_OPENGL || USE_AC_TEXTURE_MAPPER_OPENGL, in future patches we could add the proper layout if there is another options in the if.

> Source/WebCore/GNUmakefile.list.am:5078
> +if !USE_AC_CLUTTER

Same here.

> Source/WebCore/platform/graphics/GraphicsLayer.h:77
> +#if !USE(AC_CLUTTER)

Same here

> configure.ac:401
> +if test "$enable_webgl" = "yes" ||  test "$with_accelerated_compositing" = "clutter" || test "$with_accelerated_compositing" = "texmap-cairo"  || test "$with_accelerated_compositing" == "texmap-opengl" ; then

In case of clutter shouln't we check clutter library instead of GL?

> configure.ac:1160
> +AM_CONDITIONAL([USE_AC_CLUTTER], [test "$with_accelerated_compositing" = "clutter"])
> +AM_CONDITIONAL([USE_AC_TEXTURE_MAPPER_OPENGL], [test "$with_accelerated_compositing" = "texmap-opengl"])
> +AM_CONDITIONAL([USE_AC_TEXTURE_MAPPER_CAIRO], [test "$with_accelerated_compositing" = "texmap-cairo"])

I think abbreviations are not used in the defines to improve readability, even if we have a huge name, not sure if we can use just a part of it.

Just a couple minor changes to suggest. I will land this with my suggestions.

> Source/WebCore/GNUmakefile.am:568
> +if USE_ACCELERATED_COMPOSITING_TEXTURE_MAPPER_CAIRO

I think we should call these TEXTURE_MAPPER AND TEXTURE_MAPPER_GL to maintain consistency with Qt.

> configure.ac:397
> +if test "$enable_webgl" = "yes" ||  test "$with_accelerated_compositing" = "texmap-cairo"  || test "$with_accelerated_compositing" = "texmap-opengl" ; then

There's an extra space before the second "test" here.

> +AM_CONDITIONAL([USE_ACCELERATED_COMPOSITING], [test "$with_accelerated_compositing" = "texmap-opengl"])
> +AM_CONDITIONAL([USE_ACCELERATED_COMPOSITING_TEXTURE_MAPPER_CAIRO], [test "$with_accelerated_compositing" = "texmap-cairo"])

Maybe just cairo, opengl and clutter.
