also require this extention (OGL3.0), but it have one _realy_ big advantage:
- now it's possible to blit between different texture sizes, so all util draw calls can be implemented as blit
this new design will once create a texture for all chars.
while rendering a string, a list of polygons (position on screen + texture)
for this string is generated on the fly and print at once by glDrawArrays.
atm, there is no support for colors, so everything will display white.

two last draw-calls are missing:
VertexManager::Draw (see Graphic_Update branch)
RasterFont::printString (perhaps reimplement with an texture)

should be done with VAO, but atm, this is not possible :-(
this also partial revert the fix in fb92c338af (activating texture0 globally).

So to compensate lets bring back some speed to the emulation.
change a little the way the vertex are send to the gpu,
This first implementation changes dx9 a lot and dx11 a little to increase the parallelism between the cpu and gpu.
ogl: is my next step in ogl is a little more trickier so i have to take a little more time.
the original concept is Marcos idea, with my little touch to make it even more faster.
what to look for: SPEEEEEDDD :).
please test it a lot and let me know if you see any problem.
in dx9 the code is prepared to fall back to the previous implementation if your card does not support the amount of buffers needed.
So if you did not experience any speed gains you know where is the problem :).
for the ones with more experience and compression of the code please test changing the amount and size of the buffers to tune this for your specific machine.
The current values are the sweet spot for my machine.
All must Thanks Marcos, I hate him for giving good ideas when I'm full of work.
Very useful to compare performance between two builds, check the impact of
a configuration option, etc. FPS log is stored in User/Logs/fps.txt and is
reset each time you launch a game. Only enabled if you check the "Log FPS
to file" option in your graphics settings.
Could be improved a bit: currently logs only every 1s (so you can't really
see small variations), maybe output more infos to the fps.txt like
average/stddev (but Excel/Libreoffice/Google Docs can compute that easily
too).
