issue with alpha channel in from-to of selectionBarGradient

[nebulaszlonemethi]

Steps to reproduce

Configure a slider like eg.:
... selectionBarGradient: { from: "rgba(255, 0, 0, 0.15)", to: "#ff0000" } ...

Expected behaviour

The bg color of the selection bar should start at rgba(255, 0, 0, 0.15)

Actual behaviour

The bg color of the selection bar starts somewhere else because of the default bg color of the bar.

Quick workaround with css, works only on white background:

.rzslider .rz-selection[style*="background-image"] { background: #fff; }

Indeed, since the selection bar is rendered on top of the main one, this is expected.

Your workaround is nice though!
