Problems with custom buttons in Gingerbread about opentripplanner-for-android

I think the drawer rendering issue is a symptom of a few issues that I've been following related to the Maps API v2. This issue on another project has a lot of info, including some on affected devices.

The underlying problem seems to be a bug with the 'TextureView' implementation on older devices:
https://code.google.com/p/gmaps-api-issues/issues/detail?id=4659#c35

There are workarounds, but the underlying problem doesn't seem fixable. If we do a workaround, we should make sure it only runs on older devices with the problem, since I found that some of the workarounds cause noticeable performance problems.

I have changed the buttons to a flat/rounded corners/semi transparent version (witch look nice, maybe even better than the drop shadow version) for devices older than API level 11 as they don't have the drop shadow used for newer devices, which crashed this icons. Other non important things were changed for all devices (as line separators colors from Holo blue to gray) and theme and all panels and activities are defined with a withe background and use a light theme (compatible with all devices).

I didn't made the pull request because I want to do some more testing and I don't have always access to these devices with API level lower than 11.

The problem with the TextureView is not solved because I don't have too much time right now to fix bugs and I also think that this is not so important as background works well if user taps on the panel.
