Synopsis of the Bitmap Button Control Revision:

Set 'bitmap' console field to the names of one or more bitmaps to use for specific states of the control as described below...

Usage in persistant field assignment:
bitmap = ;

Usage in method call:
obj.setBitmap();

::= [[ ]]
::= \[_]
::= [[]]
::=
- single image used for all states (implies nhdi)
n - name is normal state image - button up, mouse elsewhere

is limited to 511 characters in length maximum
extension (.png, .gif, .jpg) is optional

Examples:
from gui script as persistant field assignment:
bitmap = "./UpArrow";
bitmap = "./UpArrow_n ./UparrowRed_h ";
bitmap = "./UpArrow_n ./UparrowRed_hd ./UparrowGrey_i";
as method call:
setBitmap("./UpArrow");
setBitmap("./UpArrow_n ./UparrowRed_h ./UparrowRed_d");

In the examples above, the image UpArrow is a normal state image, UpArrowRed is used as a highlight and a down state image, UpArrowGrey is used as an inactive state image.

If no bitmap is found the control will render a default bitmap.
If the extent is set to (0,0) in the gui editor and apply is pressed, this control will set its extent to the size of the normal bitmap (if any).
