Use the high-resolution data to render the preview.
We now use high-res data, instead of low-res data, to render the viewfinder/preview mosaic.
This results in a much better quality in viewfinder/preview mosaic.

Updates to remove compile warnings and stop the viewfinder panning at UI boundary. Also, new logic for rendering the preview mosaic.
1) Fixed compiler warnings reported by Wei-Ta.
2) The viewfinder now stops panning (for both left-to-right and right-to-left motions) when it hits a pre-defined border region within the screen viewport.
3) Updated the logic for rendering to always maintain the preview mosaic (previewFBO) in the current-frame coordinate system. This fixes the repeating issues.

Updates to allow the viewfinder to slide across the UI with device panning. Also, rendering updates for color conversion using GPU.
1) Refactored the SurfaceTextureRenderer and WarpRenderer classes to inherit from a new base class Renderer.
2) Fixed a minor bug in the Blend class and added a helper function to create the mosaic in middle frame coordinate system [no changes in run-time behavior].
3) Added a flip-flop gPreviewFBO to allow panning the viewfinder across the UI when the user pans the device.
4) Fixed the size of the viewfinder and preview mosaic to match the UI layout height.
5) The viewfinder in the preview stage is now aligned with the viewfinder in the capture stage.
6) Added new class YVURenderer that converts from RGB to YVU data using GLSL shaders.
7) Modified the rendering pipeline to use GPU for RGB to YVU conversion. The processing thread now only performs conversion from YVUA interlaced to YVU planar format.
8) Updates following Wei-Ta's code-review comments.

Updates to allow using SurfaceTexture for reading the preview frames directly from GPU memory.
1) SurfaceTexture is now used to obtain the data processed by the mosaicing library.
2) SurfaceTexture in GPU memory is directly rendered using the transformation from the mosaicing library to generate the preview mosaic.
3) GPU is also used to generate the Low-Res frames from the High-res frames (was being done in CPU before).
4) SurfaceTexture is also used to render the viewfinder as soon as the mosaicing application starts (eliminating the need for a separate SurfaceHolder to render the camera).
5) Modified the XML layout during the preview state to be the same size as during the capture stage to accommodate the SurfaceTexture based viewfinder [this needs to be reviewed and adjusted].
6) Fixed the viewfinder and back button issues identified by Wei-Ta.
7) Round-1 of removing trailing spaces and tabs.
8) Added documentation to new Java side interfaces and cleaned up code in general.
9) Cleaned up redundant and commented out code from the native side.
10) Merged with latest updates from the main trunk.
11) Fixed issues identified in code review and also cleaned up and refactored some code.
12) Added layout-w1024dp/pano_capture.xml for tablet layout.

Updates for mosaic preview rendering to happen using native GLES2.0 code.
1) Added new subfolder mosaic_renderer in feature_mos/src with FrameBuffer and WarpRenderer classes.
2) Added mosaic_renderer_jni.h|cpp files to the jni folder to perform GL calls for rendering on the GL thread.
3) Updated code in feature_mos_jni.cpp to connect with mosaic_renderer_jni.cpp.
4) Added new java files in com.android.camera.panorama to encapsulate the GL JNI interface, a GLSurfaceView for display and a GLSurfaceView.Renderer for rendering.
5) Modified APP code to enable the new GL-based rendering and made relevant changes to the UI (in pano_views.xml).
6) Fixed a GL bug which was preventing the rendering from working properly after hitting the back button once.
7) Preview rendering now displays in the current frame coordinate system.
8) Fixed the ghost preview rendering bug.
