[PATCH 1/1] winex11.drv: Don't add MWM_DECOR_BORDER to windows without a caption.

[Dmitry Timoshkov]

From: Dmitry Timoshkov

Also don't use MWM_DECOR_RESIZEH, window resizing is controlled by MWM_FUNC_RESIZE.

This patch fixes double caption observed under some WMs (Metacity, its
successor Mate, and XFCE), they always treat such windows as requesting
the caption decoration.
