Glitch effect applies to first 200px of text only

We are forced to use unit-free $width and $height, so it's impossible to make it responsive (as we are non-standard units to size each element).

Perhaps we could write 2 SCSS mixins to:

• strip unit from number;
• get number's unit;

… then somehow use them in the glitch mixin.

Not sure how to fix this using the mixin. Perhaps we can use some SVG magic instead.
