X-Git-Tag: archive/raspbian/50.5-1+rpi1~1^2~897^2^2~110

theme-node-transition: Receive a CoglFramebuffer

This is in preparation for a future where only explicit frambuffer
APIs are available, i.e., cogl_get_draw_framebuffer() does not
exist.

There is absolutely no functional changes in this patch (nor the
following ones in this series), only rearrangements so that various
functions receive a CoglFramebuffer instead of using the draw
framebuffer.
