This is the ANGLE project from:

http://code.google.com/p/angleproject/

The upstream version used here can be found in:

src/common/version.h

This copy of the library has been modified with several patches
that can be found in the 'patches' subdirectory.

Updating ANGLE
-------------------------------------------------------------
To update to a newer version of ANGLE, extract the archive
directly into the 'src/3rdparty/angle' directory. ANGLE contains
a .gitignore file that will overwrite the one in Qt, but this is
not desirable so the ANGLE one should be discarded and the one in
Qt should be kept. If there are new source/header files in ANGLE
(git status -u) then they should be added to the relevant .pro
file before committing.


Using a custom ANGLE
-------------------------------------------------------------
Qt supports building a version of ANGLE other than the one that
is contained in the source tree. To get Qt to build a different
copy of ANGLE, you can set the ANGLE_DIR environment variable
to point to the location of the custom ANGLE before building Qt.
