Subject: [PATCH] LEGO1: MxPalette (#56)

* MxPalette - add missing member variables, Detach function

* mb

* MxPalette: give bob the builder his constructor

* push progress, gn

* avoid hexadecimal

Co-authored-by: Anonymous Maarten <madebr@users.noreply.github.com>

* fix MxPalette::GetDefaultPalette

Co-authored-by: Anonymous Maarten <madebr@users.noreply.github.com>

* aaaaaaaaaaaaaa

* Revert "fix MxPalette::GetDefaultPalette"

This reverts commit 63f2215737d3bcd286f67dcf1a04fdf8a234d41b.

* Implement MxPalette::Clone (doesn't match)

* fix MxPalette structure and match ctor/dtor

* Matching progress for MxPalette::GetDefaultPalette

* Implement ApplySystemEntriesToPalette except the memcpy calls

* implement SetSkyColor (doesn't match)

* Use MxTypes instead of generics

* prefer decimal values than hex for m_entries

* Update mxpalette.cpp

* Push MxPalette progress - read comments in code.

* improved MxPalette::operator==, will be 100% when MSVC feels like making it so

* improved MxPalette::SetSkyColor, will be 100% when MSVC feels like making it so

* improved MxPalette::Clone, will be 100% when MSVC feels like making it so

* Fixes

- reordered the functions in order of where they are in the hex because recmp.py sometimes kept saying it couldn't find the symbol (??)
- clone returns a pointer, not a ref
- worked a bit on setpalette/applysysentriestopalette

* Match GetDefaultPalette a bit more

* fix: MxPalette::GetDefaultPalette is now 100% matching

* fix: MxPalette::ApplySystemEntriesToPalette is now 100% matching

* tidy: rename `DC` var in GetDefaultPalette to `hdc`

* fix: MxPalette::SetPalette is now functionally matching

Not assembly matching yet because of MSVC weirdness.
At some point it will probably start matching, because
the structure seems to be accurate.

* fix: MxPalette rgbquad ctor functionally matches

Not quite ASM matching yet because of weird
register allocation mismatches.

* fix: I forgot to commit mxpalette.h...

* tidy: use Mx* primitives instead of builtins

* refactor: remove MxPalette::FromBitmapPalette

* fix: call ApplySystemEntriesToPalette from MxPalette(const RGBQUAD *)

* rename MxPalette::SetPalette to MxPalette::SetEntries

* fix: I once again forgot to commit mxpalette.h...

* feat: add/match MxPalette::Reset [0x100BF490]

* fix: add MVideoManager() to mxomni header

* refactor: change unk50 in MxVideoManager to LPDIRECTDRAW

* feat: add/match MxPalette::CreateNativePalette [0x100BF000]

* fix: MxPalette::SetSkyColor is 100% matching

* Annotate MxPalette members' offsets

* Annotate the global default aplette

* use hex size

* remove unnecessary variable offset listing

* Update LEGO1/mxpalette.cpp
