The finding was that 99% of the time, textures are static in memory. However, Dolphin would pessimistically continue to decode and copy the same texture every time. The optimisation is to check if the texture matches what is in the cache, and if it does, Dolphin should early exit.
The result is the speed in New Super Mario Bros Wii increased 35% with spinning coins. Still not as fast as EFB copy to texture though.

Upon texture reloading, the cache entry hash wasn't updated and thus we effectively disabled any texture caching in that case.

Games affected by this change: Mario Smash Football, Mario Strikers Charged Football, Monster Hunter Tri.
Other games possibly affected: Shaun White Snowboarding, Resident Evil Code: Veronica, Baten Kaitos.
This implementation will decrease performance if the game uses this feature, but the glitches will be gone. I'll add an option for this in a later commit. EFB pokes are somewhat slow in DX11 right now, speed should be okayish in DX9 though.
Other changes:
- SOMEWHAT cleaned up the EFB access code in DX9
- Fixed incompatible parameter list of AccessEFB and TVideo_AccessEFB.
- Fixed a theoretical bug in ReplaceRGBATexture2D, add support for STAGING textures
- Removed unused parameters in various DX9 functions

Now, there are two:
Real dimensions: Width and height of the original GameCube texture
Virtual dimensions: Width and height of the texture used by dolphin-emu's renderer

Work around different gcc versions giving conflicting warnings
about signed/unsigned comparisons involving bit fields.

Renamed EFB Scale to Internal Resolution.
Removed Auto Scale option (it is now always on).
Added on-the-fly changing of the Internal Resolution in the OpenGL and Direct3D9 plug-ins.
Further consolidated the code in the video plug-ins.

final rendering of (at least) Sonic Unleashed.
This should be (nearly) invisible in Z16 depth copies and in games, but there is
some chance that it collides with other such border cases. There probably is some
room to decrease the adjustment but 9999999/10000000 is not enough. A static offset
may be an option, too. I don't know if the game can/does set something like that.

for all the plugins implemented per pixel lighting, this will make games that uses lighting a lot nice. (just look at mario sunshine and compare :))
for dx9: implemented temporal anaglyph stereo: just grab your red-cyan glasses and enjoy.
stereo calibration: use stereo separation ( distance of the point from you are looking) and Focal Angle: the angle necessary to focus in one particular object.
this settings are different in every games as they use different depth ranges.
please for any regression and bug introduced by this commit.
if you ask why i did not implement stereo in dx11 and opengl the reason is one: they don't work right when i have more time will try to find a way to make them work.

Main Issues:
DX11 is functional with a ~2MB/s mem leak.
OpenGL/DirectX9 have a black display while game runs. (DirectX 9 flashes good display on emulation stop)
Too many virtual function calls. (once everything is working, I will work on removing them)
Won't build on non-Windows in its current state. (mainly EmuWindow will need changes for Linux/OS X)
Probably other stuff.

include referenced array data in the hash to avoid problems in some games.
this version is a slower than the last version but is more stable, still much work to do but so little time to do it :)
Added Dlist Caching Option to the plugin configuration so anyone can compare the performance change.

still experimental, not totally optimized but must bring a nice speed up
please test for regressions an error. an please Linux people fix scons :)

use plain vertex arrays instead of VBOs to render in Opengl plugin as the nature of the data make VBOs slower. This must bring, depending on the implementation, a good speedup in opengl.
in my system now opengl and d3d9 have a difference of 1 to 5 fps depending of the game.
some cleanup and a little work pointing to future improvements in the way of rendering.
please test and check for any errors.

fixed one of the last graphic problems in smg, now the glow in the plants and planets must be correct.
the error was caused by a error in lighting calculations. so it must affect other games.
please test and let me know the results.

Really that happens because the fifo.CPReadWriteDistance is negative.
Example: CPReadWriteDistance: -864 CPEnd: 10092672 fifo.CPBase: 9568416
In SMG this is because PI_FIFO_RESET is writing and after fifo.CPReadWriteDistance will be setted to 0.
To Prevent that, I've Implemented AbortFrame function in the CommmandProcessor. It should fix overflown because of that.
Note: There is other issue (Issue 2846) where the fifo.CPReadWriteDistance is negative too but the effect is different.
I'm working to solve this.

I am not sure i am understanding what the pipeline really does, and more so what
the GC/WII expects here. If my comments are incorrect, please let me know.
This was tested with MP2:E, ZWW on r6075.

Remove a member variable which I introduced in r5907 although it never actually got used. Restores binary compatibility (at least in that regard) to pre-r5907 video plugins, but breaks any binaries after that :P
Update FIFO watermark tightness recommendations. 1000 is quite a high value I guess, but some people seem to need it.

The code changes disable the usual pipeline flush for certain BP Writes that occur while the minimap is being drawn in Zelda: twilight princess. This significantly increases speed while in hyrule field. The way this is accomplished is described more in depth on page 42 of Xtreme's thread. Big thanks to Xtreme for doing a great job hosting that thread, and Kiesel-stein for initial work on the hack
Also, I used the resource editor in Visual studio to generate the GUI code for the DX11 plugin, and some code appeared to be removed, although the behavior of the GUI did not seem to change. Hopefully someone more experienced with resource files (forms?) can double check that no code was damaged
