/**
* Allows a new format for width, height, offset-x and offset-y in the bar section
* Allows a new format for pixel sizes (like width in the bar section)
*
* The new format is X%:Z, where X is in [0, 100], and Z is any real value
* describing a pixel offset. The actual value is calculated by X% * max + Z
* The max is the monitor width for width and offset-x and monitor height for
* the other two
