-----------
[Filters] Use CGStyle-based filters for brightness(), contrast(), invert()
and opacity()
https://bugs.webkit.org/show_bug.cgi?id=299063
rdar://160822033
Reviewed by Simon Fraser.
These CSS filters are translated to FEComponentTransfer effects which have to be
applied in unaccelerated software mode. Having one of these effects in the CSS
filter chain (e.g. "filter:invert(1) blur(10px);"), prevents gaining the high
performance of the CGStyle filters for the whole chain.
Similar to what we do for CA filters, these effects should be translated to
FEColorMatrix.
