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.

I am officially killing the local/global build crap. The "local" build thing should never have existed. There is now only one build that is essentially what the "global" build was before. This is the way a proper build system should work. I will soon write a wiki page to describe how to properly use the cmake build system, and how you can still set things up to get the "local" build from before. However, that type of build should be considered a developer tool, and not the way that dolphin-emu should be built.
Briefly, to use cmake now do the following from the toplevel of dolphin's source:
mkdir Builddir
cd Builddir
cmake ..
make
make install (you may need superuser privileges)
Note that the scons build is still building dolphin in the old way.

Explanation of this commit: We only have to care about four BP registers in ClearScreen, the remaining API state should be reset. The colorEnable and alphaEnable parameters are obsolete, for some reason directly using them caused the SMS glitch with DX11 (because of that bpmem.zcontrol.pixel_format == PIXELFMT_RGBA6_Z24 check in BPFunctions.cpp, is this one actually correct?)
The comment in BPFunctions.cpp was at least misleading (if not even wrong), so I removed it.
For what it's worth, someone needs to port this to the OpenGL and Software plugins (unless they're doing this properly already)

Some notes about this:
- config.h doesn't get written yet, so you'll have to use one generated by SCons
- dependency checking isn't really implemented, yet. Just some basic checks for OpenGL or ALSA, we need something more sophisticated though.
- the OpenGL plugin fails to load for some reason which I can't debug right now due to the libc debuginfo package version in openSUSE not matching the runtime packages
- there's even some support for generating install packages (rpm/deb/.. packages, NSIS installer, etc). It doesn't work properly right now though, since some paths seem to be hardcoded into Dolphin's source
- probably lots of other stuff I forgot... Just take a look at all the TODOs in the CMakeLists.txt files for more information ;P
Additionally, I added various files to the svn:ignore list.
tl;dr: Unless you are a dev or you're building binary packages, this commit shouldn't bother you :P

Fixes issue 3399.
Also remove unnecessary stateman/gfxstate applies:
- gfxstate->ApplyState/Reset only need to be called by VertexManager
- stateman->Apply only needs to be called before any Draw/DrawIndexed call

Small performance improvements by increasing the ring buffer size and using a better offset algorithm.

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

The "Enable Progressive Scan" option in the Wii menu now controls whether the Wii/GC will detect a progressive scan display. This affects the timing of some games (both GC and Wii). Usually, the checkbox should be unticked as progressive scan displays require higher bandwidth.
This fixes the slow speed in NBA JAM. This also fixes the hang in Megaman Network Transmission. This should fix Deadly Creatures (turn off progressive scan).
Fixes issue 3314.
Fixes issue 3066.
Fixes issue 2571.

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

- Add a sanity check in CRenderFrame::MSWWindowProc. Possibly reduces the risk of a crash when starting a game and immediately closing the emulation window when using the DX9 plugin.
- DX11: Add the resource usage as a parameter to CreateQuadVertexBuffer, possibly to be used in the future.
- reduce the size of the EFB access buffers from 4x4 to 1x1 since they needn't be bigger anymore
- some fixes to the recent hires commit.

Should fix SMG for NVIDIA users. Slightly changes behavior of the AccessEFB function, so test this for regressions, please (esp. in HD resolutions).
I tried to apply the same changes to Video_DX9, but for some reason EFB access didn't work anymore then. Might look into that later.
