+================================================================================
+Added an experimental tool (bitmap2component) to create logos from .bmp bitmaps. Added Potrace library to convert bitmaps to polygons
+    This tool uses potarce library that converts a bitmap picture (.bmp or .pgm format) to a set of polygons.
+    bitmap2component converts a bitmap to a .emp footprint (that can be imported by modedit) or a .lib component that can be
+    imported by libedit.
+    Note: imported bitmaps logos are vectored by potrace, so there is no pixelation effect.
+    Scale is 1:1 for 300ppi pictures.
+    bitmap2component currently runs only is command line mode
+    run
+        bitmap2component bitmapfile.bmp bitmapfile.lib 1 to create a schematic component logo
+        (import this file using libedit)
+        or
+        bitmap2component bitmapfile.bmp bitmapfile.emp 1 to create a footprint logo
+        (import this file using modedit)
