##Generate a weston.ini file:

To modify any of the default sections (core, shell), add a
do_configure() function to your bbappend, using machine (e.g. h3ulcb)
overrides (i.e. use the MACHINE name where "machine" is used below):

'''
do_configure_machine() {
    echo repaint-window=34 >> ${WORKDIR}/core.cfg

    echo transition-duration=300 >> ${WORKDIR}/ivishell.cfg
    echo cursor-theme=default >> ${WORKDIR}/ivishell.cfg
}
'''
or:
'''
do_configure_machine() {
    sed -i -e 's/drm-backend/fbdev-backend/' ${WORKDIR}/core.cfg
}
'''

To add new non-display sections, just list them in SRC_URI and WESTON_FRAGMENTS:
'''
FILESEXTRAPATHS_prepend_machine := "${THISDIR}/${PN}:"

SRC_URI_append_machine = " file://foo.cfg"
WESTON_FRAGMENTS_append_machine = " foo"

'''

To change the display, for example from the default assumption of an
HDMI-1-A connected screen that needs to be rotated 270 degrees to one
that is rotated 90 degrees, redefine the WESTON_DISPLAYS variable:

'''
WESTON_DISPLAYS_machine = "hdmi-a-1-90"
'''

Note that the weston-ini-conf recipe automatically generates a landscape
orientation version of weston.ini by replacing 90/270 degree rotation
fragments for HDMI-A-1 and the virtual output into 180 and 0 degrees,
respectively.  This landscape configuration can be used in an image by
pulling in weston-ini-conf-landscape instead of weston-ini-conf.
