This bypasses a declaration in the script in favor of a simpler implementation. In order to work it is always necessary to have an offset table to map the variables to, but doing it fully on the native side only requires adding the type to the declaration.
- fixed: divisions wasted one register for each operation due to a double allocation.
- changed math operations to use less registers. There was a well-intended change to allocate the destination first, but the better approach is to first allocate the operands and free then before allocating the destination register.
- added support for global variables to the code generator - not the compiler, though. For the handful of entries this is needed for it may just as well be done manually. So far FLevelLocals level is the only one being exported.
- fixed: The VM disassembler truncated 64 bit pointers to 15 digits because the output buffer was too small.
- resolve entire FxSequences instead of aborting on the first failed entry. This allows to output all errors at once.
* Revert "Modify CMPJMP to produce more compact code (as far as VC++ is concerned, anyway)"
This reverts commit 6ff973a06b.
This modification did not work and broke the comparisons. Actually this had three problems:
* the asserts checked the wrong instruction
* the mask was not applied to regular comparisons.
* incrementing PC before testing does not work because 'test' references the PC.

Daedalus triggers this with a 0x85 character which in Windows CP 1252 is the ellipsis (...) The converter will assume ISO-8859-1, though, but cannot do anything with these characters because they map to the font being used here.
- These require manual detection and overriding of the scaling factors to
0, because a right shift of (32-0) bits wraps around to 0 and results in
no shift at all rather than leaving the register zeroed out.
- dc_destorg is normally set to the upper-left corner of the view window.
If there is a border, then this won't coincide with the upper-left
corner of the screen, and DCanvas::FillSimplePoly would merrily write off
the end of the screen buffer.
- exported thinker iterator and drop item chain to scripting. Unlike its native counterpart the script-side iterator is wrapped into a DObject to allow proper handling for memory management.
- fixed: The VMFunctionBuilder only distinguished between member and action functions but failed on static ones.
- fixed: FxAssign did not add all needed type casts. Except for purely numeric types it will now wrap the expression in an FxTypeCast. Numeric handling remains unchanged for both performance reasons and not altering semantics for DECORATE.
- exported all internal flags as variables to scripting. They still cannot be used in an actor definition.
- make ATAG_STATE the same as ATAG_GENERIC. Since state pointers exist as actual variables they can take both values which on occasion can trigger some asserts.
- gave PClass a bExported flag, so that scripts cannot see purely internal classes. Especially the types like PInt can cause problems.
Todo: we need readonly references to safely expose the actor defaults. Right now some badly behaving code could overwrite them.
Changed a description in usdf_zdoom.txt to be more truthful. It's not just one new field anymore.
(I really should learn to read these things before changing them.)
