Description
A community memory posted a sample file that they claimed worked in 4.1.1 but not in 4.2 I took a quick look at the file in question and there is an image on the page that has a colour space that uses a type 4 function. In version 4.1.1, the image comes out blue which is incorrect. In 4.2 the image render correctly because of the type 4 function support but is extreme slow.
The slowdown is because each colour is value is run thought the type 4 function. The function has no caching so when processing a 2 colour image we do a lot of extra work.

Added a calculated result cache to the type 4 function. Should have put this in in the initial release as there is significant slowdown when using an type 4 function for an image colour mask.
