Skip shadow if window is maximized or tiled

[velitasali]

Hi,

I don't think the extension needs to expose a setting for this.

Let me know what you think!

Closes #6.

Hi @velitasali , change style of shadow is a good way, thanks for great works. Confirmed that shadow has been skipped when window are tiled / maximized.

There are still a small problem, because the shadow has been clear before set style, it will occurse flash when change shadow of windows.

A solution is just clear style when window is tiled / maxmized, instead of clear it then apply again.

I will fix this problem later, thanks for contribution.
