Address an unavoidable loop phase inside color clean function where it iterates all over the graph points if data used is an ArrayBuffer. This causes graph to have way less performance relative to Array types.

There was a problem hiding this comment.
Let's only allow typed arrays here by using the isTypedArray function.
Lines 8 to 11 in 65f739d
To use that you could require it like this:
var isTypedArray = require('../../lib/array').isTypedArray;

Does this PR fully resolve #4401 i.e. the part about line-decimation or just the part about Arrays? |

Address: #4401
Overview of the Pull Request:
Address an unavoidable loop phase inside color clean function where
it iterates all over the graph points if data used is a derivative of a ArrayBuffer.
This causes graph to have way less performance relative to Array types.
Also added a little performance enhancement to calc function. Tell if this is out of scope :)
