ad9455f9ff - ossengine: Reduce number of requested fragments again slightly to 6, because OSSv4 has a default minimum fragment size of about 10 ms causing excessive minimum latency.

f267e2a5cd - ossengine: Fix horribly broken rate estimation on OSS4 (and possibly other implementations) by using GETOPTR rather than GETOSPACE.
- ossengine: Increase number of fragments requested from 4 to 8 for more accurate OSPACE/OPTR information with OSS4 (and possibly other implementations).
- ossengine: Minor include corrections and namespace fixes. Use log(x)/log(2) rather than non-c++98 log2. Minor rounding fix in fragment size calculation.

0d83920ade - Use RGBA internal texture format, as it usually means less conversion.
- Get rid of pointless initialization of OpenGL state that is equal to 
the default, or otherwise meaningless. Enable GL_CULL_FACE in case it's 
slightly faster in some configurations.

c2938c3eb8 - Add data structure that efficiently keeps track of the minimum of a
small, fixed set of variables, using templates to autogenerate 
efficient, unrolled functions that update the binary tree for each 
variable. It also efficiently supports priorities among variables when 
their values are equal, and can give variables that change the most 
frequently a better spot in the tree if the number of variables isn't a 
power of 2. Will be used for event scheduling.

4b4d05e309 - Add basic WASAPI engine with exclusive mode support. Latency and rate estimation is generally better than DirectSound, and
in exclusive mode there is less blocking as well as exclusive mode being better than shared mode in the other areas too.

probably invalid.
- RateEst: Allow using a custom timestamp in feed().
- RateEst: Keep a queue of the last ~100 msec worth of samples and duration, and filter out collective
  samples that give a pre-estimate that seems way off.

d9edc2e78d - Direct3DBlitter and DirectDrawBlitter: Force blocking updates when sync to vblank is enabled.
Some updates only block if there's a prior unfinished update in progress. This screws up frame time estimation
  in turn screwing up vsync. To fix this we do a double update (and extra blit) if close to a frame time
  period has passed since the last update when sync to vblank is enabled. I really should have noticed this earlier
  as it pretty much breaks vsync adaption completely.
- Direct3DBlitter: Use the D3DCREATE_FPU_PRESERVE flag when creating device. Omitting this flag can screw up floating point
  calculations in other parts of the code. For instance WASAPI cursor timestamps get utterly screwed up here.
- Direct3DBlitter: It appears that managed textures are updated before they are unlocked, which screws up redraws, making
  things appear choppy in some situations. Use a default memory texture and a system memory texture and the UpdateTexure
  method instead.

beb4f51f5f - Adaptively skip BlitterWidget syncs if audio buffer is low, in a manner that should minimize wasted skips in sync to vblank situation, and tries to be non-disturbing. This replaces frame time halving, and blitter specific rescueing.
- 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.

d7203ffd32 QGLBlitter: Do a cheap front blit rather than a vsynced flip if audio buffers are low.
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.

9feeeed04d - Add CoreAudio engine with rate estimation and buffer status support. Default engine on Mac OS X.
- 44100 Hz default sample rate on OS X, since OS X tends to resample everything to 44100 Hz.

- Extend ringbuffer.h to support resetting size, and move it to common dir since gambatte_qt/coreaudioengine uses it too now.
