+ * Name: nxtk_bitmaptoolbar
+ *
+ * Description:
+ * Copy a rectangular region of a larger image into the rectangle in the
+ * specified toolbar sub-window.
+ *
+ * Input Parameters:
+ * hfwnd - The sub-window twhose toolbar will receive the bitmap image
+ * dest - Describes the rectangular region on in the toolbar sub-window
+ * will receive the bit map.
+ * src - The start of the source image.
+ * origin - The origin of the upper, left-most corner of the full bitmap.
+ * Both dest and origin are in sub-window coordinates, however, the
+ * origin may lie outside of the sub-window display.
+ * stride - The width of the full source image in pixels.
+ *
+ * Return:
+ * OK on success; ERROR on failure with errno set appropriately
+ *
