+TWAIN Plug-in

+
+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.
+ 
+Debugging:
+ There are two different versions of the program included, a standard
+ version and a version built for debugging.  The debugging version is
+ a special version capable of capturing the TWAIN datasource data to
+ a file for later processing.  This feature can be used to create a data
+ dump that can be sent to me if for some reason the plug-in fails for
+ your TWAIN datasource.  The function of the plug-in is controlled by
+ the name of the executable file.  The plug-in should be placed in your
+ plug-ins directory and named as follows:
+
+twain.exe - This is the standard (non-debugging) version.  This file will
+  not behave differently if renamed.  This version is intended to be used
+  unless your TWAIN datasource has some problem.
+
+gtwain.exe - This is the debugging version of the program shipped along.
+  If this program is used as named, it will behave the same as "twain.exe"
+  except that the file C:\twain.log will be written.  This file is a text
+  file with very little information available for debugging.
+
+dtwain.exe - Renaming "gtwain.exe" to "dtwain.exe" in your plug-ins directory
+  will change the behavior of the plug-in.  The menu option will be registered
+  as "TWAIN Acquire (Dump)..." and will cause the TWAIN acquire operation to
+  be dumped to the file "C:\twaincap.bin".  This file contains all of the data
+  necessary to recreate the capture on another system (such as my machine).  The
+  image will not be displayed, as it might cause the plug-in to crash making
+  the data useless.  Instead, a message will be displayed that the image
+  information was dumped to a file.
+
+rtwain.exe - Renaming "gtwain.exe" to "rtwain.exe" in your plug-ins directory
+  will change the behavior of the plug-in.  The menu option will be registered
+  as "TWAIN Acquire (Read)..." and will cause the TWAIN acquire operation to
+  read a previously dumped (using dtwain.exe) TWAIN acquire from 
+  "C:\twaincap.bin".
+
+If you find that you are unable to capture data from you datasource (the plug-in
+crashes or the image is wrong), please capture data using the following steps:
+
+1) Copy gtwain.exe to your plug-ins directory as "dtwain.exe".
+2) Run GIMP.
+3) Choose Xtns->TWAIN Acquire (Dump)...
+4) Choose the datasource settings that are causing problems.
+5) Choose a *SMALL* sample image.
+6) Zip up "C:\twaincap.bin" and "C:\twain.log" and send them to me.

+ * 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.

+ * 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.

+                                 Change DC to TW
+                                 Change filename from DC.H to TWAIN.H
+    version 1.5, July 1993.      Remove spaces from country identifiers
+
+    version 1.7, July 1997       Added Capabilities and data structure for
+                                 document imaging and digital cameras.
+                                 KHL.
+    version 1.7, July 1997       Inserted Borland compatibile structure packing
+                                 directives provided by Mentor.  JMH
+    version 1.7, Aug 1997        Expanded file tabs to spaces.
+                                 NOTE: future authors should be sure to have
+                                 their editors set to automatically expand tabs
+                                 to spaces (original tab setting was 4 spaces).
+    version 1.7, Sept 1997       Added job control values
+                                 Added return codes
+    version 1.7, Sept 1997       changed definition of pRGBRESPONSE to
+                                 pTW_RGBRESPONSE
+    version 1.7  Aug 1998        Added missing TWEI_BARCODEROTATION values
+                                 TWBCOR_ types JMH
+    version 1.8  August 1998     Added new types and definitions required
+                                 for 1.8 Specification JMH
