* improved sprites processing accuracy.
* fixed VBLANK transition line checks.
* code cleanup and (minor) optimizations.

[Core/Sound]
* increased FM internal sample size to 32-bit to avoid overflow when adding channels.
* added preliminary emulation of YM2612 DAC precision (can be configured to match real console output).
* added configurable roll-off for FIR filtering in High-Quality FM mode.

[Wii]
*added support to enable/disable Video Encoder Trap Filter: can help reproducing "color blending" as on a real Genesis (composite video only).
*added support to configure Video Encoder gamma correction.
