overlay: optimize blit() to not perform a blit if the active item rect is empty.
It seems that in EVE Online, if we update our overlay texture but do not
draw to the screen, the texture mapping is never freed, until we begin
drawing again.
I do not know enough D3D11 to know why.
Instead, this commit works around the issue by introducing a fully legal
optimization to the blit() method:
If the rect of active overlay elements is empty (that is, the screen is
empty), do not perform a blit at all.
The change also introduces an extra call to blit upon receiving
OVERLAY_MSG_ACTIVE. That message is the message that signals that
the rect of active elements has changed.
We need to blit here to ensure we redraw correctly once the rect
of active overlay elements changes.
Fixes mumble-voip/mumble#1123
