The function IMOVERLAY creates a mask-based image overlay. It takes input image and a binary mask, and it produces an output image whose masked pixels have been replaced by a specified color.

NOTE: This original implementation of IMOVERLAY was superseded in R2016a by a new function, with the same name, in the Image Processing Toolbox. The version here has been renamed to IMOVERLAY_OLD.

Based on a suggestion from Lasse, I added code to automatically convert the mask input to be logical.

Based on a suggestion by Matt Whitaker, I added documentation and an example explaining how to use mat2gray for double / single grayscale images outside the normal [0, 1] range.
