[webkit-dev] Feature announcement: Font Boosting

[John Mellor]

Hi webkit-dev,

You may have heard  that Chrome for
Android includes a "Font Boosting" feature. This is similar in intent to
the text size 
adjustfeature
in Mobile Safari, that the QT port also seems
interested in . Other mobile browsers have
corresponding features: Mobile Firefox uses font
inflationand IE Mobile
applies text
size 
adjustment
.

Font Boosting increases the font size in wide blocks, so that you can
easily read the text after double-tapping to fit the block to the screen,
instead of having to zoom in further then scroll from side to side for each
line you read.

The details are subtle (since web text layout is complicated), and there's
still a lot of tweaking to do. We chose to boost font sizes more than
Mobile Safari (which has various limits), producing easily legible text,
more in line with IE Mobile and Firefox Mobile.

This is core functionality for mobile browsers, so we would like to
upstream our implementation of Font Boosting to WebCore. We are keen to
share code with other ports (e.g. QT and Mobile Safari) that are interested
in this feature, and will be happy to incorporate suggestions on how to
make this easier.

I've opened webkit.org/b/84186 to track this effort.

Best wishes,
John

Re: [webkit-dev] check-webkit-style should remind folks to update the results for run-bindings-tests

I am for this idea, but in that case maybe I want the option to ignore
run-bindings-tests in the build.

When we change CodeGenerator*.pm, we repeat try & error many times
until build succeeds. If we needed to update run-bindings-tests for
each try, that would be troublesome:)
