Added storing and restoring of currently bound texture, clear color
and framebuffer when recreating the FBOs. When FBOs are created
they are now created with new id's to avoid changing FBOs and textures
that are being used in the CanvasRenderNode.

With ANGLE the example in question does not show anything when drawing
with GL_POINTS. The value of gl_PointSize is undefined when not written
to. To be safe we set it to 1 properly in the vertex shader.

Separating the pixel size from the layout size like in HTML makes Canvas3D
behave more like the WebGL canvas and reduces delta when porting code.

This commit breaks compatibility with Qt 5.4 and earlier versions. It removes the
temporary QObject based TypedArrays and moves the code to use the native
QV4::TypedArray support in Qt 5.5. This allows the implementation now to also
add support for compressed textures and support all getParameter() values.

Starting to replace QObject pointers with QJSValue that allows dynamic
properties to be added to the the returned objects from QCanvas3D API.
This makes the implementation more compatible with WebGL code out there.

All uniform??va functions made internal, uniform??v functions now accept
QJSValue as input and dynamically detect the parameter type.
Examples updated accordingly.

Buffer3D, Program3D, Shader3D and UniformLocation3D types now changed
to use QJSValue.
