Expression function preview

[Lutymane]

Example expression:
float t = time * (1.0 - (3.5 / float(n+1)));

Highlight the time * (1.0 - (3.5 / float(n+1))); part, right click - Visualize expression [Hot Key]

Menu appears with all variables within:
time, n, where you can choose its kind - const (fixed value, which you can define), var (dimension variable, f(x1, x2, ...) ) and type - float (continuous value), int (floored value, floor(float) )

Maximum is 2 variables, since it's already 3D graph.

Use raymarching for 3D

Use the same canvas for visualizing? Or separate one inside of the modal?
