in videocommon little fix for the alpha test values, return to the original values as they are more accurate.
in D3D:
huge change in state management, now all the state management is centralized and redundant state changes are eliminated.
Fixed the overlapped viewport error in non ati cards:
the error was caused by this: when a viewport is defined larger than the current rendertarget, an error is thrown and the last valid viewport is used, this is the reference behavior, in ati cards if a larger viewport is defined, no eror is returned, the rendering is valid and is rendered using the projection defined by the viewport but limited to the rendertarget are, exactly like opengl or the GC hardware.
to solve this in reference drivers defined a large rendertarget (2x the size of the original) and proceed to render in a centered quad insithe the larger rendertarget, in this way larger viewports always falls inside a valid rendertarget size, the drawback of this is the waste of resources. it can be dynamized, depending or games or changed at runtime when a oversized viewport is detected, but i live that to future commits.
please test this and let me know the results.

- Add an option to enable the EFB scaled copy *TODO find a better place for it to go.
SOIL - Update stb_image to the latest version (1.16 to 1.18)

Also reimplemented screen clearing as a color quad to support alpha blending when clearing as in the original hardware.
the funny thing is how is implemented peeking, as locking depth textures is not supported, implemented peeking copying the values form the depth texture to a r32f render target and then reading back the data.
please a lot of testing to this commit.

first part if fixing, fixed, i thing, the flickering that everyone has reported, at least in my case i only have flickering in the one texture in one game and now is fixed. The other fix is not for an reported issue, is more a correctness fix, running dolphin with pix to review debug errors, result in a ton of warnings and error, now with this commit, at least for ati, there no more error or warnings, this means, correct management and state change, no accurate emulation, for this still a lot of work to do.
for this part of the commit please give me feedback and let me know of remaining issues
Te second part is the partial implementation of efb to ram copy in d3d, this won't brake anything because is commented but i commit this to ask for help from ector and donko in some errors remaining in the implementation related to differences between opengl an d3d.
if you want to test this you have to uncomment line 150 to 155 of bpstruct.cpp

corrected a little depth textures still broken but now at least i discover the reason, the ultra bad news for d3d lover is, the only correct way to implement depth textures will be do a firs depth only pass disabling blending.
This is because blending is affecting the values stored in the depth texture, so to store the true values, blending mus be deactivated.
this will degrade performance but is the only "Correct" way in d3d 9. the other possibility is dx10 but that's a complete different story ;)

Implemented all the correct format conversions in efb to texture copy.
replaced all the stretcrect calls with quad draws this must improve speed a bit.
A BIGGGGGGGGGG cleanup in the code and reorganization.
reimplemented zpeek using a secondary render target ( this still is buggy so many issues left)
please a lot off feedback.

d3d: remove the depth texture path it will not work so for now only lockable textures were available. i thing the only way will be a use a secondary render target and do a depth pass to mimic depth textures.
opengl: minor cleanup here and there and a possible fix to issue 1509, but not tested because in my system the errors remarked in the issue don't show.
commond: code reorganization an optimization in the pixel shader generator, trying to understand the tev stages, make some changes to make the generator faster (not much only started for the alpha test and fog).
this changes try start solving the diferences bethen the hardware plugins and the soft plugin.
i hope with i don't brake nothing but please test this a lot.

they are extremely hard/driver Dependant so your test is needed.
there plugin will automatically select the path thats work for your hard, need that everyone post the messages that the video init throw (yes all will hate me for the messages) but is the only way to see what is the optimal path. in the next commit will clean the unused paths.
i'm afraid thath the second path is Vista dependant (you need to include vista sdk to make it work).
the third path use lockable depth buffer so there is no change in that.
now peek color is fully working and is fast because the you never lock the the real color texture only the offscreen surface.
please if someone knows a game that use peek color please test it.
also fixed blending so SMS underwater must be fixed.
this work with d3d teach me that i love opengl :)

implemented buffer format fall back to allow hardware that don't support lockable formats to run the games with Z peeking disabled, applied as well the patch suggested in issue 1494 please give heavy test to this commit
git-svn-id: https://dolphin-emu.googlecode.com/svn/trunk@4365 8ced0084-cf51-0410-be5f-012b33b47a6e
Opengl:
Reorder the rendering path to make it more generic, and a little bit faster i think.
Reduce the index Buffer size to make it more Friendly to older video hardware.
get rid of the remaining annoying sps (I hope).
D3D:
Implement the same path as opengl to make the plugins more similar and maintainable.
Fixed Peek_Z this means, Pushing stars in SMG Now Works.
Please give heavy testing to this changes and compare the performance with the old path.
Thanks to hrydgard for let me participate :).
