/*
* This is a code generator. It outputs C code which can be compiled using the
* standard build tools. It is used to generate code for the DIB Blt routines.
* There are a lot of possible Blt routines (256 rop codes, for 6 different
* bit depths). It is possible to use a generic Blt routine which handles all
* rop codes and all depths. The drawback is that it will be relatively slow.
* The other extreme is to write (generate) a separate Blt routine for each
* rop code/depth combination. This will result in a extremely large amount
* of code. So, we opt for something in between: named rops get their own
* routine, unnamed rops are handled by a generic routine.
* Basically, what happens is that generic code which looks like:
*
* for (...)
* {
* if (CondA)
* {
* doSomethingA;
* }
* for (...)
* {
* if (CondB)
* {
* doSomethingB;
* }
* else
* {
* doSomethingElseB;
* }
* }
* }
*
* is specialized for named rops to look like:
*
* if (condC)
* {
* if (condD)
* {
* for (...)
* {
* for (...)
* {
* pumpSomeBytes;
* }
* }
* }
* else
* {
* for (...)
* {
* for (...)
* {
* pumpSomeBytesSlightlyDifferentE;
* }
* }
* }
* }
*
* i.e. we make the inner loops as tight as possible.
* Another optimization is to try to load/store 32 alligned bits at a time from
* video memory. Accessing video memory from the CPU is slooooooow, so let's
* try to do this as little as possible, even if that means we have to do some
* extra operations using main memory.
