If you call gegl_color_new before gegl_init, it will now try to
call babl before babl was initialized and segfault.

This changes the semantics to be line with the expected for CSS/HTML values.
Because the format can only have 256 values per channel, gamma-corrected
is also the only thing which gives sufficient perceptual precision.
Makes previously added unit tests pass.

Warn: changes output of operations using this type of format strings!

Currently failing as named and RGB hex does not interpret values as gamma-corrected.

This exectuable is useful to others using GEGL,
for instance in test suites.

Add enum GeglAccessMode { GEGL_ACCESS_READ, _WRITE, _READWRITE } and
change everything to use it. Add compat #defines for the old values.

The ones are there for the API symmetry with gegl_buffer_get's scale,
using discrete levels is probably better than the scale equivalent in
all cases.

There is overhead involved in emitting changed signals, even when nothing is
connected. This adds a wrapper function to be used instead of g_signal_connect
that tags the buffer as a buffer that should be emitting changed signals.
