lok: cleanup and simplify graphic selection code

Don't get SfxViewShell all the time, just one and ask if it is
available (non-null).
Rename sSelection to sSelectionText so it doesn't look similar
to aSelection.
Group more if statement together - especially to bring them under
bTiledRendering "umbrella"
