862518 - Make sure the thumb of <input type=range> with fractional values is drawn at the correct position with Cocoa native theming

Status: RESOLVED FIXED

(Core :: Widget: Cocoa, defect)

Description

[Jonathan Watt [:jwatt]]

When an <input type=range> with native theming is given fractional values on OS X, its thumb is often positioned in the wrong location. It turns out this is due to rounding when assigning double values to int values in the theming code.
