320x240 touchscreen - CabbieTabs

[csussman]

I've been working on a theme for the iBasso DX50/90 for the past 3 years or so on and off. It should also work for the cowon D2 with some changes.
I got the idea from the redbox theme to make a wps with tabs for changing settings and viewing track info.
The wps is mainly finished except for some minor adjustments; The sbs still needs a lot of work.

I made a round slider for the progress bar (using magenta for the corners), but instead of seeing the progress bar behind the left corners I see the backdrop (See the third screenshot). Is there any way around this?
