no OVERRIDE on blink API implementation

[Marijn Kruisselbrink, 2014/09/11 17:57:52]

Done. But why is this? Is this to make it easier to change signatures on the
blink side? Also BlinkPlatformImpl does have OVERRIDE for at least part of its
blink API implementation...

[jochen (gone - plz use gerrit), 2014/09/12 13:52:54]

yes, to make it easier.

Apparently not everybody knows this and adds the OVERRIDE macros automatically,
however, the clang plugin will not complain for blink API if you don't
