/*
* This is some tricky shiz. So detailed explanation follows:
*
* The main issue here is that pde enhancements like color vars, # literals
* and int() type casting deviate from standard java. But I need to exact
* index matching for pde and java versions of snippets.For ex:
* "color col = #ffaadd;" <-PDE version "int col = 0xffffaadd;" <-Converted
* to Java
*
* For exact index mapping, I need to know at what indices either is
* deviating from the other and by what amount. Turns out, it isn't quite
* easy.(1) First I take the pde version of the code as an argument(pde
* version fetched from the editor directly). I then find all instances
* which need to be converted to pure java, marking those indices and the
* index correction needed. (2) Now all java conversions are applied after
* marking the offsets. This ensures that the index order isn't disturbed by
* one at a time conversions as done in preprocessCode() in ECS. Took me
* sometime to figure out this was a bug. (3) Next I create a tables(two
* separate arrays) which allows me to look it up for matching any index
* between pde or java version of the snippet. This also lets me find out
* any difference in length between both versions.
*
* Keep in mind though, dark magic was involved in creating the final lookup
* table.
*
* TODO: This is a work in progress. There may be more bugs here in hiding.
