[dev] [dmenu] -w crashes on transparent windows

Hi,

I am unable to use the dmenu's -w flag for windows with enabled transparency.

How to reproduce:

Start a bash session in st and type in:

$ echo -e 'abc\ndef' | dmenu -w $WINDOWID

This works for vanilla st, but after applying the alpha pull request, it crashes with
the following message:

X Error of failed request: BadMatch (invalid parameter attributes)
  Major opcode of failed request: 62 (X_CopyArea)
  Serial number of failed request: 71
  Current serial number in output stream: 72

I am currently using dmenu 4.9 from the Arch package. I had this error with 4.8
too.

Same thing happens with spacebed after applying the alpha pull request, regardless of
which application is running inside spacebed (e.g. also with surf) and whether
the windows are actually transparent.

Maybe dmenu would also need an 'alpha' pull request for this case?

Greetings,
Maciej
