So we are introducing another dependency... I guess it is alright, but can you check with Simon?

This breaks the (native) build on Windows and technically it also requires changes on non-Windows to get the include path right. zlib.h isn't _guaranteed_ to be in /usr/include strictly speaking. If possible we should be using pkg-config then (and I guess on mac we can rely on fixed paths).

Options for Windows I can think of:

1) No support the feature there (urgh)
2) Pull in src/3rdparty/zlib.pri from the Qt sources (tricky)
3) In addition to 1 or 2, introduce the _option_ of building against a shared zlib on Windows with the ability to specify the include path and library path (or make take implicitly through INCLUDES/LIBS env)

Simon's comments imply this should be r-.

New regression level down occurred!

We have applied the patch a few month ago, and it goes well with html5test.com & css3test.com which both use WOFF web fonts.

But now, all sites suddenly broken down.

QtWebKit-2.3.2, which has contained this patch, built based upon Qt-4.8.x, also fails on css3test.com.

Since css3test.com uses web font files hosted on Google, i surpose that the font file formats have changed recently???

[Chen Zhixiang]

css3test.com uses "text-shadow: 0 -.1em .2em black;", the newest Chrome 29.0.1547.57 m cannot display this text-shadow effect, while Firefox 23.0.1 can.
