Snaking sliders initial implementation.

Browse Source 
Draws curves in a range from 0 to x (where x is a value between 0 and 1) while blending them in (if enabled in the options)
Cache a unit-cone once and re-use that with scaling and translation instead of generating it each time again.
This is more for readability than performance (since presumably feeding it mostly constants like before would be faster)

Only draws the cones in the curve once if possible
(only possible if consective calls to draw with the intervals x_1 before x_2 are made and [0, x_1] [0, x_2] with x_1 < x_2 holds true)

minor refactoring and cleanup

Omg my code is such a mess. I feel like I've committed a crime against humanity by just randomly putting that
random vbo id into the class called "Rendertarget". But there's really no good place for it now (that has a way to clean it up).
But if "Rendertarget" will ever be used by anything else but the sliders I'm gonna pull that out.

added blending in for return arrows and ticks
