Display frame number in view 1.1 for Maya (maya script)

File is .mb Maya 4.5 scene.
Has only been tested on Mac, but should work on other platforms, since no system or file handling is done. Its just a simple expression.

File is a scene which contains camera->locator->annotation.
The annotation displays the frame number and custom text.
The locator is movable and can be placed anywhere, I've put it in the top left corner in the persp view.
The custom text can be edited, see the expression.

Very useful when playblasting.
