Tianjie Xu b8564e1093 Adjust the background text image width to reduce its size 
We can adjust the image width with respect to the maximum width of the
wrapped text. This will remove some black margins and reduce the final
size of the images, especially for those with short strings, e.g.
"recovery_error".

Also, add an option to centrally align the text; and fix a boundary
check in the recovery resource test.

Test: Generate and check the image

Recovery Image Generator

This program uses java.awt.Graphics2D to generate the background text files used under recovery mode. And thus we don't need to do the manual work by running emulators with different dpi.

Usage:

java -jar path_to_jar --image_width imageWidth --text_name textName --font_dir fontDirectory --resource_dir resourceDirectory --output_file outputFilename

Description of the parameters:

  1. imageWidth: The number of pixels per line; and the text strings will be wrapped accordingly.
  2. textName: The description of the text string, e.g. "recovery_erasing", "recovery_installing_security"
  3. fontDirectory: The directory that contains all the support .ttf | .ttc files, e.g. $OUT/system/fonts/
  4. resourceDirectory: The resource directory that contains all the translated strings in xml format, e.g. bootable/recovery/tools/recovery_l10n/res/
  5. outputFilename: Path to the generated image.
