Bug Description

[Impact]

Trying to remove and/or re-add window decorations using xprop does not work. Compiz expects that _MOTIF_WM_HINTS property type is _MOTIF_WM_HINTS while xprop use CARDINAL type.

[Test Case]

xprop -f _MOTIF_WM_HINTS 32c -set _MOTIF_WM_HINTS "0x2, 0x0, 0x0, 0x0, 0x0"

Use this command from terminal and then select window from which to remove decorations. Decorations should disappear from selected window.

To re-add decorations use this command:
xprop -f _MOTIF_WM_HINTS 32c -set _MOTIF_WM_HINTS "0x2, 0x0, 0x1, 0x0, 0x0"

[Regression Potential]

Metacity and Mutter also use AnyPropertyType when reading _MOTIF_WM_HINTS property so I guess there should be no regressions.

Verified that 1:0.9.12.3+16.04.20171116-0ubuntu1 fixes the issue on xenial: before upgrading, I confirmed xprop didn't disable the decorations on an xterm window; after upgrading, it did.

Thank you!
