"Glue layers can greatly simplify the porting of applications from one software environment to another. The concept of a "glue layer" becomes especially practical when there is a large body of already-debugged application software, and it's not desireable to recode that software to a new, different programming interface."

"This is especially common with graphical applications because, once painstakenly coded, no one wants to reinvest the effort to overcome all the "off-by-one" problems and other issues associated with graphical systems interfaces. In addition, a well-designed large body of software -- including graphical "stacks" which include framebuffer code, windowing systems, widget sets, and applications software -- needs to use layered software techniques in order to achieve code and component independence."

"Because the Microwindows Project is very well architected by splitting it's own functionality into well defined, separate components, it is fairly easy to write a glue layer that allows a major component of Microwindows to talk with a new or unknown programming interface."
