Changes to resolve jagged horizontal edge and blurred vertical edge issues.
1) Made the strip width and cross-fading parameters absolute pixel values.
2) Updated the above parameters to use thinner strips with lower cross-fading radius.
3) Added another parameter to limit the number of pyramid levels at which cross-fading is applied.

Fix an OOM issue in mosaic blending.
Set two limits on when we will do mosaic blending.
1) mosaic_width * mosaic_height < (5 * frame_width) * (2 * frame_height)
2) mosaic_height < 2.5 * frame_height
The latter limit rejects blending for the cases having too much movement
in the secondary direction.

Eliminating aliasing vertical lines.
Reduce the cross-fading factor to eliminate the aliasing vertical lines.
Also, fix an issues in blending: skipping cross-fading when the
cross-fading width is 0.

Avoid a possible overflow on setting the mosaic size.
Log the size of the mosaic image before cropping, so as to help debug.
Also, fix another issue that NV21 should be vertically subsmapled.

Updates to handle textureless scenes during capture.
1) Starts stitching only when the camera sees a textured scene at the beginning.
2) If a texturess scene is encountered in the middle of a capture, the stitching continues with the intermediate frames translated using the pan velocity estimate.
3) Added more error codes and percolated them up to the java layer.
4) Fix a build error in Mosaic::addFrame() and added comments.
5) Update the javadoc in Mosaic.java to reflect the new returning codes.

Bug fixes to the cropping region selection algorithm.
1) The library should now return proper error code for the negative width scenario.
2) Also fixed a round-off issue which lead to improper cropping behavior for low-res output.

Updates to allow cancellation of mosaic computation from a UI trigger.
1) reportProgress now takes a new boolean parameter that can be used to break out of the mosaic computation loop at the library level.
2) Added a cancel button to the progressDialog and a new Handler message to handle the button click so that the user can be taken back to the capture stage.
3) Updates to address the code review.

Fix a monkey bug - a null pointer issue in native.
A monkey report shows that we try to generate a mosaic even before we
added any frame to the aligner. This is unlikely to be triggered by human
actions but machine generated sequences. To fix it, we ensure that we do
blending on frames only after we have accepted frames in aligner.

Updates to allow the mosaic library to report the mosaic computation progress (both low-res and high-res).
1) Added a new method to the Mosaic class that reports the percent progress for both LR and HR mosaicers.
2) Added a test function to the activity that logs the reported progress.
3) [REMOVED] Added a test progress-bar to the UI for quick testing of the progress reporting UI.
4) Made minor updates in response to Wei-Ta's review.

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.
