1355716 - stylo: Consider supporting color overriding pref

Status: RESOLVED FIXED

Description

[Xidorn Quan [:xidorn] UTC+10]

There is a feature in Options that allow user to override all page with colors they specify in "Contents / Fonts & Colors / Colors / Override the colors specified by the page with your selections above:".

We may need to support it.

It is controlled by pref "browser.display.document_color_use", and test_dont_use_document_colors.html checks it.

This is where Gecko uses that: http://searchfox.org/mozilla-central/rev/2fc8c8d483d9ec9fd0ec319c6c53807f7fa8e8a2/layout/style/nsCSSDataBlock.cpp#44-50

I wonder whether it is better to reuse `PropertyFlags`... Probably not here.
