* 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
*
