## Transform GRanges with New Coordinates

### Description

For graphics, like linked plot, e.g. generated by `qplotRangesLinkedToData` function in package ggbio. we need to generate a new set of coordinates which is used for even spaced statistics track.

### Usage

      transformGRangesForEvenSpace(gr)

### Arguments

`gr` | A GRanges object.

### Details

Most used internally for special graphics, like `qplotRangesLinkedToData` function in package ggbio.

### Value

A GRanges object as passed in, with new column x.new which indicate the static track coordinates, in this way, we could map the new coordinates with the old one.
