As a reminder to myself, and hopefully helpful to others and the Codejock devs:

To make MatrixTransform work as a RenderTransform in CJ 22.0.0, I had to make the following changes:

- Source\Markup\XTPMarkupContext.cpp -> Add registrations to parser

Add:

#include "Markup/Transform/XTPMarkupMatrixTransform.h"

#include "Markup/Transform/XTPMarkupGdiPlusMatrixTransform.h"

in void CXTPMarkupContext::RegisterClasses(), add:

CXTPMarkupGdiPlusMatrixTransform::RegisterType();

- Source\Markup\Transform\XTPMarkupGdiPlusMatrixTransform.cpp Simply use the transformation:

BOOL CXTPMarkupGdiPlusMatrixTransform::TransformMatrix(const CXTPGdiPlus* pReserved,
                                                       GpMatrix* pMatrix)
{
   UNREFERENCED_PARAMETER(pReserved);

   ASSERT(NULL != pMatrix);

   const int matrixValues               = 6;
   CXTPMarkupDoubleCollection* pValues = GetMatrix();
   if (pValues->GetCount() < matrixValues || matrixValues > pValues->GetCount())
       return FALSE;

Matrix m((Gdiplus::REAL)pValues->GetAt(0), (Gdiplus::REAL)pValues->GetAt(1),

(Gdiplus::REAL)pValues->GetAt(2), (Gdiplus::REAL)pValues->GetAt(3),

(Gdiplus::REAL)pValues->GetAt(4), (Gdiplus::REAL)pValues->GetAt(5));

   if (Gdiplus::Ok != GdipMultiplyMatrix(pMatrix, &m, Gdiplus::MatrixOrderPrepend))
       return FALSE;

   return TRUE;
}

- Source\Markup\XTPMarkupObject.cpp Support floats with powers (e/E):

BOOL CXTPMarkupDoubleCollection::GetNextValue(LPCWSTR& lpszValue, float& fValue)
{
   while (*lpszValue != '\0' && isspace(*lpszValue)) lpszValue++;
   if (*lpszValue == '\0') {
        return FALSE;
   }

   WCHAR* lpszEnd;
   fValue = wcstof(lpszValue, &lpszEnd);
   auto result = lpszValue != lpszEnd;
   lpszValue = lpszEnd;
   return result;
}

With these changes, all the Axialis XAML icons I'm using in my project work.
