Changelog:

Jun 13, 2009 - r98, r97, r96
r98 - win32 - add internal audio buffer for avi writer
r97 - totally forgotten about gui_used things, added
r96 - separated "Lua drawings in image" from "Text in image", gui.gdscreenshot now overlays uncommited Lua drawings if needed. something nasty: replaced _WIN32, __WIN32, __WIN32__ to WIN32 :/

Jun 07, 2009 - r95
fixed GCC screwup on the Linux build resulting in a segfault at startup

Jun 06, 2009 - r94
Fix Linux compilation errors

Apr 26, 2009 - r92
Quick fix for the issue that the current working directory is changed by snes9x, the script host. (I think this fix is incomplete, when a function which is provided by snes9x changes the current directory unintentionally, the current directory will be lost anyway)

Apr 24, 2009 - r91
added gui.clearuncommitted for easy flicker reduction when gui.register can't be used

Apr 21, 2009 - r90, r89, r88, r87, r86
r90 - added a option to switch the color conversion method of gui.gdscreenshot
r89 - stupid fix to the issue that joypad.set sometimes disables user input after script dies.
r88 - Change to ignore "max skipped frames" during fast-forward when using fixed frameskip mode.
r87 - Adjusted fixed frameskip mode to run in 100% speed, as well as auto frameskip mode.
r86 - improved gui.popup (win32), added input.popup

Apr 20, 2009 - r85, r84, r83, r82
r85 - Small SFMT changes.
r84 - Changed the draw timing of Lua GUI (use gui.register to display something)
r83 - more convenient hotkeys setup for frame/lag counters
r82 - added "Clean FastROM setting" sync option to fix playback of old movies of certain FastROM games that need an improperly-initialized emulator value to sync, fixed options in the movie recording dialog not working if another movie was already open, increased V1_RR_UNOFFICIAL to fix support for loading old savestates (which might be embedded in some movies)

Apr 19,2009 - r81, r80, r79, r78
r81 - Added source position/size parameters to gui.gdoverlay. Modified movie drag and drop code.
r80 - made gui.gdoverlay act like it does in Gens (nitsuja was faster! but mine supports indexed images as well, so I overwrite the code, sorry >_<), removed the upper limit of opacity.
r79 - made gui.gdoverlay act like it does in Gens (i.e. full transparency support, coordinates are optional, extra transparency modifier allowed), and unrestricted input.get mouse coords
r78 - Hi-res support for gui.gdscreenshot, Added StretchScreenshots to cfg file.

Apr 18, 2009 - r77, r76
r77 - keyon savestate fix (at least, 1.51 needed this)
r76 - obc1 savestate fix

Apr 15, 2009 - r75, r74
r75 - desync fix for some variables not getting reset upon hard reset, and fix for snapshots saving NULL pointers in a fragile way
r74 - more savestate desync fixes (mainly superfx and hdma)

Apr 13, 2009 - r73
more savestate desync fixes

Apr 12, 2009 - r72, r71, r70
r72 - fixing several savestate desync issues
r71 - Replaced math.random and math.randomseed with SFMT version, because C rand's quality is bad, generally speaking.
r70 - made the savestate compression level configurable in the emulator settings menu, and chose a faster compression level as the default

Apr 10, 2009 - r69, r68, r67, r66, r65
r69 - added gui.getpixel, saved lua filename to config so reload will work across sessions, added savestate.verify in debug for catching/testing desyncs, minor script load dialog improvements
r68 - Added a few of more members to savestate (btw, as far as I tested, r66 fixes a frequent desync in Goemon 1&4 at least)
r67 - Changed Debug build setting due to issue 11. (IIRC, when I applied that change before, there was a fatal trouble that snes9x didn't emulate a ROM after loading it. But that doesn't happened in this time. I don't know why, anyway I commit the change for the time being.)
r66 - [HIGHLY EXPERIMENTAL] Added some of members which are added since 1.5x. I don't know whether these fix existing desync, and I haven't tested the change enough. Anyway, I'd like to investigate about existing desyncs I know when I have enough time. (To developers: don't forget to clean your outputs before you try to build)
r65 - [EXPERIMENTAL] Stored lagcounter things to the official savestate.

Apr 08, 2009 - r64, r63
r64 - tried to fix issue 10 (http://code.google.com/p/snes9x143-rerecording/issues/detail?id=10)

r60 - Reverted S9xLuaClearGui() timing :/
r59 - Added something ugly which is not used after all (24/32 bit color version of render method for Lua GUI)
r58 - fix for leaking .luasav files of anonymous savestates
r57 - input.get added

Mar 30, 2009 - r56
fixing a bunch of warnings, turning up the Release mode optimization level, and adding a vcproj.user file to make Lua script reloading not insanely slow by default when running from the debugger in Release mode (if you've opened the project before, you'll have to delete your snes9xw.vcproj.COMPUTERNAME.USERNAME.user file for this last change to take effect)

Mar 29, 2009 - r55, r54, r53, r52
