When the preferred visual returned by EGL is different from the parent
window's visual, a private colormap is needed in the call to
XCreateWindow. See X server source code
http://cgit.freedesktop.org/xorg/xserver/tree/dix/window.c#n708
This patch systematically creates a TrueColor XColormap, regardless of
the visual returned by eglGetConfigAttrib().
Fixes#9997
