winemac: Use a snapshot of an owned window when a zero-sized owner window is minimized.

Some apps create a zero-sized window as their "main" window and then create all of the other top-level windows as owned windows with that main window as the owner. The user interacts with these owned windows. When the user attempts to minimize one of these owned windows, the app instead minimizes the zero-sized owner window. When an owner window is minimized, all of its owned windows are hidden. The Mac driver faithfully carries out these window operations. The only visible windows are hidden and the zero-sized window is minimized. This results in an invisible animation of the window down to a slot in the Dock - a slot which appears mostly empty. The invisible window thumbnail is badged with the app icon, but it still looks strange. On Windows, the Alt-Tab switcher uses the image of the owned window to represent the zero-sized owner. This commit attempts to do something similar. It takes over drawing of the Dock icon for minimized, zero-sized window. It grabs a snapshot of one of the owned windows and draws the app badge onto it. Since the owned windows are hidden before the zero-sized owner is minimized and we can't take snapshots of hidden windows, we use heuristics to guess when it may be useful to grab the snapshot. If the user minimizes an owned window from the Cocoa side, we grab that window's snapshot. If an owned window is being hidden and no snapshot has been taken recently, we grab its snapshot on the theory that this may be the beginning of hiding all of the owned windows before minimizing the owner. Unfortunately, this doesn't address the invisible animations when minimizing and unminimizing the zero-sized owner window.
