HSliders and VSliders in Flex

Another infuriatingly well documented feature from Flex. Having spent an considerable amount of time trying to skin a VSlider using the trackHighlightSkin with an embedded clip - it was somewhat of a surprise to discover you need to create your skin's for an HSlider; Flex then rotates these into the vertical - so all your height and width settings are flipped around.

Another well documented feature from Flex. [Grumble].
