[request] waitVanish with parameter Region/Match should wait until region content changes --- use 1.1.4+ and observe

[Zed]

When I have a region that I define as using find(), for some reason when I call waitVanish on that region it crashes Sikuli (ie, waitVanish(img.find(img2)) or waitVanish(find(img)). Didn't have this problem before on 1.0.1.

Here's the debug logs:
[debug] Region: waiting for M[92,339 212x32]@S(S(0)[0,0 1280x800]) S:1.00 C:198,355 [6/6 msec] to vanish
[error] Region: doFind: invalid parameter: M[92,339 212x32]@S(S(0)[0,0 1280x800]) S:1.00 C:198,355 [6/6 msec]
[error] ***** Terminating SikuliX after a fatal error 999 *****
It makes no sense to continue!

the java docs from waitVanish:

 /**
  * waits until target vanishes or timeout (in seconds) is
  * passed (AutoWaitTimeout)
  *
 * @param <PSI> Pattern, String or Image
 * @param target The target to wait for it to vanish
 * @return true if the target vanishes, otherwise returns false.
public <PSI> boolean waitVanish(PSI target) {

in version 1.0.1 using any other kind of parameter (like in your case a Match object as a result from find(image)) should have evaluated to an error message: image file not found on disk.

This is irritating, so in 1.1.0 it correctly reports wrong parameter in your case.

If you want to wait for an image to vanish, that just was found (in 1.1.0):
waitVanish(find(image).getImage())

... but your idea makes some sense:
waitVanish(someRegion)

where someRegion is a Region or Match object could mean:
wait until the content of the region changes.

I make it a request bug, to have this convenience shortcut.
