[Viewer3D] MediaLoader: Send pointSize as is

`pointSize` was divided by 100 before being sent to the shader that
rendered the programmable points, and was used as is to set the size of
the "fixed size" points implicitly in the QML.

Now that both cases are handled by the same shader, we do not need to
perform this division here: it will be done directly in the shader (by
opposition, keeping it here would have meant performing a x100
multiplication in the shader for the "fixed size" case).
