Søren Sandmann Pedersen 9cbcb5bd6a Use new pixman_glyph_cache_t API that will be in pixman 0.28.0 
This new API allows glyphs to be cached in a data structure in pixman,
and entire glyph strings to be composited in one go.

Also bump pixman dependency to 0.27.2.

Results from the cairo peformance test suite running against Xvfb with
a screen size of 1680x1050@32bpp:
