Themes: Only kill launchers if overlays or icons changed

There is no need to kill the launcher for every coponent changed.
The only ones that really concern us in regards to killing launchers
are MODIFIES_OVERLAYS and MODIFIES_ICONS

Add ANT to the list of toggleable airplane mode radios

Adding ANT to the list of toggleable radios allows ANT to behave in the same way as Wifi or
Bluetooth in regards to operation during airplane mode: when airplane mode is turned on, ANT is
disabled, but can be re-enabled by the user at any time.

TODO: Provide drawable for usb storage (someone please).
core: use 'normal' value for notification led off

Users can set this value to 250, 500, 1000, 2500 or 5000ms only,
but it's 2000ms by default.

With this patch, 'Normal' string is shown instead of 'By default'
and pulse speed goes to 1 sec.

watermark: Place watermark in the bottom-right when both deltax and deltaty are 0

The default behavior is to replicate the watermark all over the screen but this can
be too intrusive. The repetition is controlled by deltax and deltay and if they are
both 0 the watermark will actually be drawn off-screen and thus not shown.

We take advantage of this to add a special behavior when they are both 0 that simply
places them in the bottom right. This patch doesn't take UI elements into account and
may actually overlay soft-buttons and other chrome.

Optimize drawBitmapMesh using TRIANGLE_STRIP

Draw BitmapMesh using STRIP instead of TRIANGLES.
Depending on where the bottleneck is located in the pipeline,
there is a potential for saving two-thirds of the time spent rendering.
The speedup is due to avoiding redundant operations,
i.e., mapping each vertex four times to texture and color attribute,
sending each vertex twice to the GPU, vertex processing of GPU ...

In this patch:
1. Refactoring mesh using Strip.
2. Batch triangles by adding degenerate triangles.
3. Optimize computing positions of texture and color attribute.

Benchmark: Drawing Bitmap(1152x768 px) with 200x200 meshes
Performance is doubled (from 26.4 fps to 53 fps, Nexus10).
Memory footprint: only 17% of original method.
(from 240000 to 40401 vertices with xy, uv, rgba data.)
