 //
 // TODO(erg): There's still a lot that needs ported or done for the first time:
 //
 // - Render and inject the omnibox background.
 // - Make sure to test with a light on dark theme, too.
 
 // Work around a header bug:
 // linux/debian_wheezy_i386-sysroot/usr/include/linux/stddef.h redefines NULL
 // to 0, which breaks -Wsentinel. Get back the normal definition of NULL.
 // TODO(thakis): Remove this once we update sysroots.
