* Start MxBackgroundAudioManager
* Match MxBackgroundAudioManager constructor. This took WAY too much time.
* add size assert
* improve readability of MxBackgroundAudioManager::Enable
While the previous iteration wasn't incorrect, it definitely reads like pseudocode (i.e. it's very unlikely any actual developers would have written that). This is much more readable/likely to have been written and still results in the same asm.

* All of the MxVectors share an inheritance chain. MxVector4 inherits
from MxVector3 which inherits from MxVector2.
* They all operate on a shared `float*` data member which points to the
underlying storage.
* There are also MxVector3/4Data classes, which inherit from Vector3/4,
but add concrete storage for the Vector data rather than just an
abstract data pointer.
* The same is true for MxMatrix, with there being an abstract and a
concrete variant of it.
* Also improve reccmp.py register matching algorithm. It previously
could not recognize an effective match when a swap had to take place
between two registers used on the same line. It turns out this happens
a lot in floating point math code so I adjusted the implementation to
break the disassembly lines on spaces rather than just linebreaks
allowing the existing effective match code to handle that case too.
* Checkpoint to show MxTickleManager::SetClientTickleInterval match.

Merging in the missing functions from my pull request for MxDirectDraw on the main repo. Credit to @foxtacles for the GetPrimaryBitDepth function. All match 100% on reccmp except ErrorToString, but the problem there is with the jump table at the end.

* Implementation of MXIOINFO. Not a 100% match, but we are very close. I don't wanna wrangle with this one any more, so I figured I would open it up for review in case anyone else has ideas.
**Known problems:**
- The Open function uses a `movzx` instruction on the value of parameter `fdwOpen` before pushing to OpenFile from the kernel. You can force this to appear by casting to `unsigned short`, but this disturbs the instructions for the rest of the file. To get the "best" overall match I decided to leave this out.
- Flush, Advance, and Descend differ only in the order of operands on a `cmp` instruction.
- This entire file is honestly pretty ugly. The main reason is all the nested ifs; we are constrained by returning a result value from each function, but only at the very end instead of bailing out with a `return`. By far the worst offender is the do/while loop in the Descend function.
**Design considerations:**
- We are casting the file handle from MMIOINFO to `HFILE` everywhere it is used, so I decided to just change the type. While doing that, I figured I might as well just pull out the members from the struct so we don't have `m_info` all over the place.
- Without using a struct member, we have the issue of the obvious `memset` used to zero out the values in the constructor. I changed this to work on the object itself, which would not be valid in most cases, but seems fine here since we have no virtual methods.
There is a lot of repeated code here, namely the call to `_llseek` to reset `m_lDiskOffset` based on the current file position. You could move this to an inline function, but maybe that's not appropriate.
There are probably strides to be made on code clarity and comments (if needed or wanted) here. I'm open to any suggestions.
* remove casts on read, add size assert
* Use more Mx* types and param style convention
* Fixing up MXIOINFO to prepare for merge.
* Following feedback from @stravant and @itsmattkc, reverted back to using `MMIOINFO` struct as the class member instead of adding its values directly. (We actually gained a little on accuracy with this change.)
* The memset to zero out the values in the constructor now acts on `m_info` instead of `this`. Strictly speaking we don't need the size assert any more but I decided to keep it in case we change the members later for some reason.
* Casting the `hmmio` member to `HFILE` (int) or `HMMIO` (WORD) typedefs where needed.
* Squelch a signed/unsigned type comparison warning
* Match MxDSChunk ctor/dtor
* Push work on MxDSAction/MediaAction/Sound
* MxDSMediaAction constructor is matching up to a mov location
* Match MxDSSound constructor by adding the missing member
just four bytes in between them in ghidra.. isn't that enough for ghidra to justify a member variable?

Followed the hint from @madebr in #31 that the next function in MxString was operator+. The one after that is operator+= and both are at 100%.
Squashed commits:
* Removed unnecessary consts
* Replaced malloc/free with new/delete, which solved swapped regs in operator=
* Use delete[] when freeing char* m_data
Was intended as a simple code improvement, however it also seems to make WinMain, MxString::operator=, MxDSFile::Open 100% (all of which just needed registers to be switched around)
* match WinProc
* minor accuracy improvement
* WndProc at 50%
* fix WM_DISPLAYCHANGE branching
* fix type
* fix x/y comparison
* WndProc 82%
* 84%
* 97%
* rearrange functions to get close to the original
* remove newline
* inline no longer necessary
* merge
* 100% Match of MxDSFile
* ...almost, MxDSFile::Open is still not quite matching but all of the
other methods are 100% matching.
* Turns out that most of the virtual methods and some of the members are
actually on the MxDSSource base class, which I've pulled out as part
of this.
* In order to implement the methods I added the MXIOINFO class, which
seems to be a thin wrapper around the MMIOINFO windows structure. We
can tell this because MMIOINFO::~MMIOINFO was included in the DLL
exports, and calls down to a function which deconstructs something
looking exactly like MMIOINFO.
* Add mxdssource.cpp
* mattkc feedback
* some accuracy improvements
* Use FOURCC macro
* Tirival solve in mxioinfo.cpp
* Update mxdsfile.cpp
0xFFFFFFFF -> -1

* Use bitfield for MxVideoParamFlags
Using a bitfield for MxVideoParamFlags results in the same xor/and logic that was partially inlined in the header file. This approach is a lot cleaner and there's a good chance this is what the devs would have landed on.
The code generation is really finicky -- other inlines in the header influence the code just by being there -- so I decided to stub out all of them. This got the match to 100%.
While I was in isle.cpp::SetupVideoFlags, I changed the signature so that the `m_using16bit` parameter is just `using16bit`.
* fix: cast Set16Bit inline arg to byte
We've confirmed that, despite a function being declared inline, msvc will still make a conventional call in some circumstances. As such, I feel like this is warranted because it's most likely what a developer would have actually written.
* MxTimer::Start - swap instruction order
Technically, isRunning is set after getting the real time according to the pseudo code,
which i guess is fine, you dont know it started until it really started

I remember there being a reason why I included MxOmniCreateParambase in ISLE, but testing now it doesn't seem to be what I thought (or maybe other factors are influencing it now). Indeed it seems this is unnecessary now.
