Yet another OpenGL renderer

[nikp123]

Of course I won't be able to do this overnight because that's quite a bit to go through, I bet this is going to be three times as hard as cairo is simply due to OpenGL's inherit complexity.

[nikp123]

For those interested the development and testing of this will be in unstable and ONLY when it works (or most of these things are completed) would it be merged into master.

[nikp123]

Related #14 describes my previous attempts/struggles of choosing an ideal system for something flexible enough as this visualizer.

[nikp123]

Still deciding whether a combined draw would happen (as this is a billion times faster than drawing on separate occasions), but then again, I'm reusing the same framebuffer so it shouldn't be that bad, I believe. But yeah, this greatly diminishes the massively parallel design of GPUs and may end up being a gigantic bottleneck, we'll see.

[nikp123]

The reason why I'm avoiding merging everything into a single draw call is the sheer complexity of the variables involved and also means that ONLY ONE shader may be used, which GREATLY limits the flexibility of the system and increases it's complexity/break-ability.

[nikp123]

also no regions as that would be just a waste on time on GPU's to do anyway

status update:

1. is done
2. done
3. done
4. already use the same FBO, so it's stupid fast and efficient
5. not done, but likely not going to do it as well, because it's barely any cpu time to save
6. done by default
7. yep, this is also done
8. not done, see 5
9. yes
10. not done, yet

wayland + EGL is borked for some strange reason on the first run, considering a reset hack :)
