Previously, if you changed server's textures, textures that were not in new textures and were not in custom default textures would retain their texture from the server's old textures, instead of reverting to default.zip.
Now default.zip will always be reloaded too when you have a custom default texture pack. This does make it a little bit slower, but default.zip is simple anyways and always loading it should not really be noticable. (even on my laptop, averages ~40 ms)
This was particularly annoying, because the update checker usually finishes very quickly. So the first time you clicked the button, it didn't do anything, but the next time you clicked the button, it would actually start downloading.
web client when low performance is due to gl call overhead.

So to the best of my knowledge, there are no performance regressions.
Raspberry pi/android should also improve a little bit, but untested.
(benefit will be less as GLES calls are much cheaper compared to WebGL calls)
These measurements should be looked at as relative percent improvements, not
as absolute FPS comparisons. I did not try to properly benchmark here -
especially for the laptop, where FPS wildly varied. All these are averages.
Added documentation for compiling using visual studio command line, clarified mingw/mingw-w64 steps, add larger titles separating compiling instructions by OS
