+/* 'Viewport' conversion routines. These functions convert from one colour
+   space to another, taking into account that the source image has a smaller
+   size than the view, and is placed inside the view:
+
+        +-------view.x------------+
+        |                         |
+        |     +---image.x---+     |
+        |     |             |     |
+        |     |             |     |
+        |     +-------------+     |
+        |                         |
+        +-------------------------+
+
+   The image should always be smaller than the view. The offset (top-left
+   corner of the image) should be precomputed, so you can place the image 
+   anywhere in the view.
+
+   The functions take these parameters:
+   - width 	image width (in pixels)
+   - height	image height (in pixels)
+   - plus	view width (in pixels)
+   *src		pointer at start of image
+   *dst		pointer at offset (!) in view
