Robert Bragg bace07c0a0 Updates use of Cogl in line with api changes 
Some of Cogl's experimental apis have changed so that the buffer apis
now need to be passed a context argument and some drawing apis have been
replaced with cogl_framebuffer_ drawing apis that take explicit
framebuffer and pipeline arguments.

These changes were made as part of Cogl moving towards a more stateless
api that doesn't rely on a global context.

This patch updates Clutter to work with the latest Cogl api and bumps
the required Cogl version to 1.9.5.

# - increase clutter_micro_version to the next even number
# - increase clutter_interface_age to the next even number
# After the release:
# - increase clutter_micro_version to the next odd number

# if the API changes, set to 0. interface_age and binary_age are used to
# create the soname of the shared object:
#
# (<minor> * 100 + <micro>) - <interface_age>
#
# this allows using the same soname for different micro-releases in case
# no API was added or deprecated. for instance:
#
# clutter 1.2.0 -> 100 * 2 + 0 = 200, interface age = 0 -> 200
