2fa18d458a5545e7f6cc431954f19e136dfedc9e 23-Oct-2010 Wei-Ta Chen <weita@google.com> Fix 3118622, where tile-base jpeg decode does not handle the region
width correctly in Progressive JPEG when the h_samp_factor is different from one color
component to anothor.

To decode a region in a progressive JPEG, each time we decode
one iMCU row, the width of which equals to the region width.
However, for each color component the region width in DCT blocks depends on its h_samp_factor.
The change ensures we get a correct region width from our recorded MCU_column number.

When the sample size is larger than 1.
The calculation of image's height and width should be rounding up not down.

3147fbe7688fc353e6ae03825a37cf101a4ee01d 12-Jul-2010 Joseph Wen <josephwen@google.com> Support tile-based jpeg decoding.This change only handles the baseline case.

The functionality of tile-based decode is enabled by default.
To disable it, mark off the flag of ANDROID_TILE_BASED_DECODE in Android.mk
