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.

fourier transforms and optimal cost equations. Fast 2-tap linear as a low quality alternative.
- libgambatte: Use deltas and a running sum to decrease buffer writes in sound emulation sample generation.
- 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.
- Move non-emulation common code to a common directory to avoid duplication.
- Update front-ends to new libgambatte API.
- Utilize resampling framework in front-ends. Selectable resamplers.

- Gambatte Qt: Update AudioEngine to support sample rate estimation in terms of OS timers.
- 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: Change API to reflect MediaSources not being responsible for resampling.
- Gambatte Qt: Make sure to parent PaletteDialog list model, so it gets deleted properly.

change default buffer latency to 67 ms
don't auto-repeat buttons bound to keyboard
use enums for somewhat more robust gambattesource button setup

changed.

Add alternate key support to input settings dialog.
Auto-focus to next likely input box after settings key in input dialog.
Add "Play" and "State" input settings dialog tabs.
Avoid using the most convenient keys as forced menu short-cuts, set them
as default keys in input settings dialog instead. This unfortunately
makes the more useful shortcuts less visible, but it allows remapping
the most convenient keyboard keys.
Avoid duplicate joystick axis "press" events by keeping a map of axis
states.
Make sure to discard irrelevant/old joystick events.
Don't give MediaSource button events when stopped.
Allow joystick-based button events while paused by using a very
low-frequency poll timer.
Make some of the joystick event wrapping stuff less messy.

save state osd preview snapshots
fix a few potential security holes when loading invalid state
get rid of some undefined behaviour in statesaver
always draw in rgb32, color convert afterwards, too bad for maemo/16-bit
depth users
get rid of silly c string stuff

page flipping, triple buffering, device selection,
multi-head etc. d3d9.dll loaded at runtime
- more strict and thorough exclusive mode handling to support d3d fullscreen
- work around file open dialog not returning focus properly
- gditoggler: use current registry settings for return modes
- directsoundengine: set DSBCAPS_GETCURRENTPOSITION2 flag
- revert bad macx return from fullscreen on menu-toggle

directdrawblitter: only list devices if there are more than 2 devices (including primary)
directdrawblitter: use private static member rather than global friend enumeration callback
capitalization changes

videodialog: save actual hz values for real this time
quartztoggler: avoid potentially reverting to the wrong mode on double setFullMode(false) in multi-head configs
make sure window is within screen after mode change, so Qt doesn't reset it to the primary screen
revert to previous win32 fullscreen geometry correction behaviour so that the geometry gets properly reset after fullscreen
git-svn-id: https://gambatte.svn.sourceforge.net/svnroot/gambatte@137 9dfb2916-2d38-0410-aef4-c5fe6c9ffc24
- macx opengl drawbuffer change issues worked around
- add openal engine, default on macx
- add macx quartz video mode toggler
- multi-head infrastructure
- support multiple monitors in macx quartz toggler
- more work-arounds for Qt failing to set correct geometry on video mode changes.
- more explicit fast-forward button handling, to avoid missed key press/release events on macx
- opengl doublebuffer preblitting, try to make actual screen updates as close to right after sync wait is over as possible
- add xf86vidmode toggler (xrandrtoggler is default)
- x11blitter: check for other supported visuals if the default is unsupported.
- temporarily return to original video mode and minimize on full screen alt-tab (except on macx or if there are multiple screens), switch back on focus-in
- hide mouse cursor after move timeout, or key/joystick pressed (more sane on macx)
- exit fullscreen rather than toggle menubar on macx (note that the menubar will automatically pop-up on macx full screen if the mouse is moved to the top of the primary screen)
- add (independent) pause counter for non-client pauses.
- reset X11 screen saver on joystick activity
- change "turbo"-mode to temporarily set frametime as a way of avoiding vsync issues (for a laugh, check out the video dialog while in fast-forward mode and see "Sync to vertical blank in 65535 and 131070 Hz modes").
