Add tooltips and background images/borders to the Gauges.  

The current way of setting the background image using CSS works but is somewhat complex.  

Setting a border on the gauge does not surround the shape of the gauge, but rather results in a square.  Allow a border around the gauge's physical shape (for example, in a half circle radial gauge, the border is around the half circle), or some nicer built-in backgrounds/borders.

in the Kendo Radial Gauge chart - please give an option to display the value of the pointer near the pointer tip

Improve the gauge component by allowing reference lines to be shown along the scale.

Proposed properties

scale.reference (array of reference objects or single 'reference' object)
scale.reference.value (where between min and max)
scale.reference.width (line thickness)
scale.reference.label (same configuration properties as scale.labels)
scale.reference.line.width (line thickness)
scale.reference.line.length (radial ray length from start)
scale.reference.line.start (radial ray start from origin)

Gauge - Finer control

1. add ability to color all rendered lines/text a given color
2. Add ability to hide major minor tick marks while showing the range start/end marks

Hi, 
It would be better to show a label for the pointer shown in the linear gauge. As without the label, it would be difficult to interpret the exact value of the pointer.
