Update to 0.9.4:

0.9.2 -> 0.9.4 (r1844->r2352->r2437)

0.9.3 was skipped due to emu news sites sneaking it out of our staging area and 
releasing it prematurely while it still had bugs. I was going to curse them 
individually, but then I decided that they would just like the publicity.

 enh: more reliable and useful frameskipping
 enh: SPU: speedup: add adpcm caching

0.8 -> 0.9
 There have been so many changes that this list can hardly be considered complete.
 For this release, we have formatted the list into a high level overview of big \ 
changes and bad bugs relative to the previous release. Hopefully what you're \ 
interested in.
 This list does not include items which are solely performance boosts, for let \ 
us just say that virtually every system has been speeded up.
  
 * The savestate system is totally changed and incompatible with old savestates.
 * The 3d system should be considered rewritten.
 
General/Core:
 enh: Convert to c++
 enh: Add functions for a lid open/close. Holding key (default \ 
"Backspace" in Windows port) while game is freeze/non freeze. \ 
[CrazyMax]
 enh: Add secure area decryption from ndstool [zeromus]
 enh: Change savestate code to support loosely bound chunks and more easily \ 
other parts of the emu (GE, GPU).
      The savestate format is changed, but from now on it is in principle more \ 
resilient 
      (though it will continue to break as we tinker with the internals) [zeromus]
 enh: Added SSE2 optimizations for matrices. Since we now make an SSE2 build, \ 
more optimizations can be made. [CrazyMax]
 enh: Add a preliminary GUI hud system [CrazyMax,zeromus]

CPU/MMU:
 bug: Many fixes in IPC and GE FIFOs. Fixes freezes in NSMB, dsracing, and \ 
others. [CrazyMax,luigi__,shash]
 bug: Fix ARM instructions SBC and RSC (likewise SBC in thumb) [normatt]
 bug: Fixed Thumb LDMIA (fixes ingame Dead'n'Furious) [shash]
 bug: Fix repeating DMA (fixes NSMB parallax BG) [zeromus]
 bug: Proper handling for unaligned CPU accesses [luigi__]
 bug: Proper handling for undefined instruction exceptions [Salva Peir
 bug: correctly return vram control register values (fixes homebrew 3d games) \ 
[zeromus]
 enh: Remove 16MB of WRAM at 0x01****** from arm9. Mapped to unused instead. \ 
Nobody knows what this was. [zeromus]
 enh: Changed instruction execution to 16 at a time blocks (tested and stable) \ 
[shash]

Hardware: 
 bug: Newer and better sqrt and div emulation; makes SM64DS playable \ 
[luigi__,shash,zeromus]
 bug: Add preliminary RTC implementations [CrazyMax]
 enh: Add cosine interpolation in the SPU (conditionally compiled) [zeromus,luigi__]
 enh: Experimental: always one silent non-mixing SPU core at 44.1khz synched \ 
with emu, for more precision.
      The audible core runs with the host, causing music to slow down but not \ 
tear or pitch bend. [zeromus]

Graphics:
 - Overhaul 3d:
  . Move entire GE to core emu.
  . Move OpenGL renderer to emu core for optional use by platforms, removing \ 
ogl_collector. Now every platform shares the same 3d code.
  . Reorganize 3d code to defer rendering to after 3d vblank. Eliminates \ 
tearing, and texturing artifacts. [zeromus]
  . Add optional fragment shading pipeline (more precision) [luigi__]
  . Move lighting model to software instead of using opengl's fixed function \ 
model [zeromus]
  . Render shadow volumes; toon shading and highlight table [zeromus, luigi__]
  . Added texture caching! big speed up. [CrazyMax]
 
 bug: Many assorted tweaks and improvements to 3d and 2d precision \ 
[zeromus,CrazyMax,luigi__]
 bug: Fixes to GE: command unpacking, projection and pos-vector mode matrix \ 
handling, mult and load commands [zeromus]
 bug: Fix a bug in texture transformation mode 1 [zeromus]
 bug: Fixed GPU rendering bugs in sprites and BG [CrazyMax]
 bug: Fixes to texture conversion [CrazyMax,zeromus]
 bug: Fixes in capture display (no blinking in many games with dual 3D) [CrazyMax]
 bug: Fixes in master brightness (this fixes some games with black screens) \ 
[CrazyMax] 
 bug: Fixes in screen, backdrop, and sprite blending [luigi__]
 bug: Changed clear depths and how depth initial values are calculated (fixes \ 
SM64DS skybox, Castlevania) [shash,lugi__] 
 bug: Add 3d layer h-scrolling [zeromus]
 bug: Added transparency and fixed material alpha support and alpha testing on \ 
the 3D core [shash]
 bug: Rewrite VRAM mapping control and rendering (more accurate) [CrazyMax,luigi__]

 bug: convert colors to opengl better to prevent alpha=31 polys from being ever \ 
so slightly transparent [zeromus]
 enh: Add MMU->GPU signal for when vram mappings change to function as a \ 
texture cache invalidate signal [zeromus]
 enh: Make matrix 4x4 multiply routines use W-coordinate; carry w coord through \ 
pipeline [zeromus]
