 *
 *
 * Based on (at least) the following plug-ins:
 * Screenshot
 * GIF
 * Randomize
 *
 * Any suggestions, bug-reports or patches are welcome.
 *
 * This plug-in interfaces to the TWAIN support library in order
 * to capture images from TWAIN devices directly into GIMP images.
 * The plug-in is capable of acquiring the following type of
 * images:
 * - B/W (1 bit images translated to grayscale B/W)
 * - Grayscale up to 16 bits per pixel
 * - RGB up to 16 bits per sample (24, 30, 36, etc.)
 * - Paletted images (both Gray and RGB)
 *
 * Prerequisites:
 * Should compile and run on both Win32 and Mac OS X 10.3 (possibly
 * also on 10.2).
 *
 * Known problems:
 * - Multiple image transfers will hang the plug-in.  The current
 *   configuration compiles with a maximum of single image transfers.
 * - On Mac OS X, canceling doesn't always close things out fully.
 * - Epson TWAIN driver on Mac OS X crashes the plugin when scanning.
