Changeset 1870 for libcaca/trunk/cucul/legacy.c

Message:

• Add cucul_get_dither_brightness(), _gamma() and _contrast(). There is no reason to keep a copy of them in the calling program.
• Deprecate cucul_set_dither_invert(). Inverting a dither's colours is now done by setting a negative gamma value.
