Backported QML ShaderEffectItem from QML2.0 into Qt Quick 1.1

This issue is about backporting Scenegraph's ShaderEffectItem and ShaderEffectSource elements into Qt Quick 1.1 as a Qt labs plugin.
Purpose of these elements is to provide an interface for utilizing OpenGL shaders in QML applications.

+    and may be heavily changed or removed in later versions.
+
+    Requirement for the use of shaders is that the application is either using
+    Qt OpenGL graphicssystem or is forced to use OpenGL by setting QGLWidget as the viewport to QDeclarativeView (recommened way).
+
+    ShaderEffectItem internal behaviour is such that during the paint event it first renders its
+    ShaderEffectSource items into a OpenGL framebuffer object which can be used as a texture. If the ShaderEffectSource is defined to be an image,
+    it is directly uploaded as a texture. The texture(s) containing the source pixelcontent are then bound to graphics
+    pipeline texture units. Finally a textured mesh is passed to the vertex- and fragmentshaders which
+    then produce the final output for the ShaderEffectItem. It is possible to alter the mesh structure by defining
+    the amount vertices it contains, but currently it is not possible to import complex 3D-models to be used as the mesh.
+
+    It is possible to define one or more ShaderEffectItems to be a ShaderEffectSource for other ShaderEffectItems, but ShaderEffectItem
+    should never be declared as a child element of its source item(s) because it would cause circular loop in the painting.
+
+    A standard set of vertex attributes are provided for the shaders:
+
+    \list
+    \o qt_Vertex - The primary position of the vertex.
+    \o qt_MultiTexCoord0 - The texture co-ordinate at each vertex for texture unit 0.
+    \endlist
+
+    Additionally following uniforms are available for shaders:
+
+    \list
+    \o qt_Opacity - Effective opacity of the item.
+    \o qt_ModelViewProjectionMatrix - current 4x4 transformation matrix of the item.
+    \endlist
+
+    Furthermore, it is possible to utilize automatic QML propertybinding into vertex- and fragment shader
+    uniforms. Conversions are done according to the table below:
+
+    \table
+    \header
+        \o QML property
+        \o GLSL uniform
+    \row
+        \o property double foo: 1.0
+        \o uniform highp float foo
+    \row
+        \o property real foo: 1.0
+        \o uniform highp float foo
+    \row
+        \o property bool foo: true
+        \o uniform bool foo
+    \row
+        \o property int foo: 1
+        \o uniform int foo
+    \row
+        \o property variant foo: Qt.point(1,1)
+        \o uniform highp vec2 foo
+    \row
+        \o property variant foo: Qt.size(1, 1)
+        \o uniform highp vec2 foo
+    \row
+        \o property variant foo: Qt.rect(1, 1, 2, 2)
+        \o uniform highp vec4 foo
+    \row
+        \o property color foo: "#00000000"
+        \o uniform lowp vec4 foo
+    \row
+        \o property variant foo: Qt.vector3d(1.0, 2.0, 0.0)
+        \o uniform highp vec3 foo
+    \row
+        \o property variant foo: ShaderEffectSource { SourceItem: bar }
+        \o uniform lowp sampler2D foo
+    \endtable
+    \note
+    The uniform precision definitions in the above table are not strict, it is possible to choose the uniform
+    precision based on what is the most suitable for the shader code for that particular uniform.
+
+
+    The below example uses fragment shader to create simple wiggly effect to a text label.
+    Automatic property binding takes care of binding the properties to the uniforms if their
+    names are identical. ShaderEffectSource referring to textLabel is bound to sampler2D uniform inside the fragment
+    shader code.
