Add ANGLE as a 3rdparty library to Qt.
ANGLE is a component that implements the OpenGL ES 2.0 API on top of DirectX 9. See the following for more info: http://code.google.com/p/angleproject/ ANGLE is now the default configuration on Windows. If you want to use desktop OpenGL, you should build Qt with the following configure options: -opengl desktop To configure Qt to use another OpenGL ES 2 implementation, you should use: -opengl es2 -no-angle Task-number: QTBUG-24207 Change-Id: Iefcbeaa37ed920f431729749ab8333b248fe5134 Reviewed-by: Friedemann Kleint <Friedemann.Kleint@digia.com>

+// Symbol table for parsing. Has these design characteristics:
+//
+// * Same symbol table can be used to compile many shaders, to preserve
+// effort of creating and loading with the large numbers of built-in
+// symbols.
+//
+// * Name mangling will be used to give each function a unique name
+// so that symbol table lookups are never ambiguous. This allows
+// a simpler symbol table structure.
+//
+// * Pushing and popping of scope, so symbol table will really be a stack
+// of symbol tables. Searched from the top, with new inserts going into
+// the top.
+//
+// * Constants: Compile time constant symbols will keep their values
+// in the symbol table. The parser can substitute constants at parse
+// time, including doing constant folding and constant propagation.
+//
+// * No temporaries: Temporaries made from operations (+, --, .xy, etc.)
+// are tracked in the intermediate representation, not the symbol table.

+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.

+Date: Tue, 16 Oct 2012 10:34:32 +0200
+Subject: [PATCH 3/3] Fix Float16ToFloat32.py.
+
+To ensure generation of compilable code, the script should
+be using the alternate form of the hex string formatter to
+be sure it gets prefixed by '0x'.
+
+Also remove an extra '=' character.
+
+This issue has been reported upstream to the ANGLE team:
+
+ http://code.google.com/p/angleproject/issues/detail?id=376
