Feature/#153 webgl minimal

[leon-juenemann]

My second attempt to draw the channels with WebGL.
Now with fewer changes to the existing code structure. Was simply not feasible otherwise to merge after all the new changes.

I tried out a lot of different ways to draw the signals. In the end, I opted for this easy approach with minimal changes to the code.

Signal heads are missing. -> new ticket.

Performance is a lot better since last commit (webgl.DYNAMIC_DRAW)

[motschel123]

For me it doesn't seem like STATIC_DRAW vs DYNAMIC_DRAW makes much of a difference, but both implementation quite well on my machine. Great work

Looks very good as a base we can work with. Only have a few cleanup recommendations.

Apart from that I once again looked into the (time sweep) slider performance loss bug:
If we change the time sweep a lot we eventually run into a performance loss. This happens both in your and in the webgl-plot implementation, in yours it is merely more pronounced (earlier noticeable).

In the beginning:

After chaning the time sweep a few times:

I personally would still say we can merge this current version and build upon it with (at least) one person taking on the task of improving performance.

Works great. Good work!
