deprecated sidplay2::timebase, it always returns 1



0.2.0 2011-08-13

* ported reSIDfp engine from jsidplay2 featuring two pass resampler

* few fixes to the 6510 core based on Lorenz testuite
* added support for PSIDv3 tunes
* Updated reSID to the 1.0rc1 version (see the NEWS file in the resid dir)
* Added version defines

API changes:

deprecated method filter(const sid_filter_t *filter) from reSID builder
deprecated method filter(const sid_filterfp_t *filter) from reSIDfp builder

added method bias(const double dac_bias) to the reSID builder
The bias is given in millivolts, and a maximum reasonable control range is
approximately -500 to 500 (Actually from testing the value seems to be
in volts so dac_bias value should be in the range -0.5 - 0.5)

added methods filter6581Curve(const double filterCurve) which sets the filter
curve for 6581 chip filter in a range from 0.0 (light) to 1.0 (dark)
(default 0.5) and filter8580Curve(const double filterCurve) which sets the
filter frequency for 8580 chip (default 12500)

SidDatabase.h does not include SidTuneMod.h anymore
