- Direct3DBlitter: Use D3DSWAPEFFECT_DISCARD in non-exclusive mode.
- Direct3DBlitter: Allow triple buffering and vblank-only updates in non-excusive mode.
- Rename "Page flipping" in Direct3D and DirectDraw blitters to "Exclusive full screen".

- Clear display buffers in DirectDrawBlitter and Direct3DBlitter in exclusive mode, since blits don't necessarily cover the entire buffers.
- DirectDrawBlitter: Make sure that a minimum amount of time has passed between calls to WaitForVerticalBlank, since it can return in the same vblank period twice on a fast system.
- DirectDrawBlitter: Support vsync for refresh rate ~= 2x frame rate
- DirectDrawBlitter: Refactor somewhat and get rid of a couple minor potential bugs.
- DirectDrawBlitter: Some tweaks to get updates closer to sync time in certain situations.
- DirectDrawBlitter: Some tweaks to better support DO_NOT_WAIT.
- DirectDrawBlitter: Make only updating during vblank while page flipping optional.
- Direct3DBlitter: Some tweaks to get updates closer to sync time in certain situations.
- Filter out very short frame times in frame time estimation.
- Don't adjust frame time during turbo, but rather skip BlitterWidget syncs to speed up, which avoids vsync limits without disabling vsync.

Allow BlitterWidgets to opt in to get paintEvents while unpaused. Do so for QGLBlitter since it may need to clear buffers afterwards.
QGLBlitter: Try to blit right after sync in the case of single buffering.

Revert to big f'ing switch hq2x code, as there's less duplication now. Also optimized interpolation functions further. No idea how I missed that initially.

- 44100 Hz default sample rate on OS X, since OS X tends to resample everything to 44100 Hz.
- Get rid of buffer status averaging in OpenAlEngine, since it makes assumptions on usage pattern that shouldn't be made.
- Extend ringbuffer.h to support resetting size, and move it to common dir since gambatte_qt/coreaudioengine uses it too now.

Add RateEst reset method. Initialize RateEst count to 1.
Less refresh rate estimation averaging.
Allow more refresh rate estimation deviation.
Return NULL paintEngine in windows blitters that use the PaintToScreen attribute.
Add checks for things not being initialized in DirectDraw-blitter and QPainterBlitter paintEvents.
Don't reparent blitters (mainly to make a bug in Qt 4.4.3 win less annoying, widgets that do internal reparenting are still affected).
Check for window position less than screen top-left after mode change, before full screen, to avoid Qt moving it to the primary screen.
Add rate estimation to DirectSound engine.
Better underrun detection in DirectSound engine.

as it's not really a per source thing at this point. If resampling avoidance is desired, then that
should rather be a user option (to depend on the OS for resampling, which is mostly nonsensical for the Game Boy/NES/PSG-system case btw).

Use half frame time if audio buffer is close to underrun.
Provide combined audioengine write and status get, to avoid doing potentially expensive operations twice. Utilized in OSS and ALSA engines.
Saner vsync estimate variance protection.

Audio buffer command line options.
Use half video frame sleep time if audio buffer is close to underrun.
Adjust estimated frame time each frame.

fourier transforms and optimal cost equations. Fast 2-tap linear as a low quality alternative.

- libgambatte: Rearrange sound emulation event loop to optimize for high-frequency event units.
- libgambatte: Initialize palette arrays to avoid valgrind noise.
- Don't do resampling in libgambatte. Update API to reflect this.

- Gambatte Qt: Implement sample rate estimation in ALSA and OSS audio engines.
- Gambatte Qt: AlsaEngine: Revert to using snd_pcm_avail_update for buffer status since snd_pcm_delay may consider external latencies.
- Gambatte Qt: AlsaEngine: Use snd_pcm_hw_params_set_buffer_time_near. Don't request a particular number of periods per buffer.
- Gambatte Qt: AlsaEngine: Use hw as default custom device string, rather than hw:0,0.
- Gambatte Qt: OssEngine: Don't trust GETOSPACE fragment info.
- Gambatte Qt: Estimate optimal frame rate based on sample rate estimations.

- Gambatte Qt: Change API to reflect MediaSources not being responsible for resampling.
- Gambatte Qt: Make sure to parent PaletteDialog list model, so it gets deleted properly.
- Various refactoring, small changes and stuff I forgot.
