FPDFAnnotGetInkListPath and FPDFAnnotAddInkStroke is not working

[torfluor]

I apologize if it's just be being dumb, but to me it looks like adding and reading ink annotations is not working at all.
Both FPDFAnnotGetInkListPath and FPDFAnnotAddInkStroke should take a pointer to an array of FS_POINTF_ as the argument, but in the generated PDFiumCode.cs code the parameter is defined as global::PDFiumCore.FS_POINTF_ points and not a pointer. I manually modified the points parameter to IntPtr and after building the package both reading and adding ink annotation works.

I changed FPDFAnnotAddInkStroke from

public static int FPDFAnnotAddInkStroke(global::PDFiumCore.FpdfAnnotationT annot, global::PDFiumCore.FS_POINTF_ points, ulong point_count)
{
    var __arg0 = annot is null ? __IntPtr.Zero : annot.__Instance;
    var ____arg1 = points.__Instance;
    var __arg1 = new __IntPtr(&____arg1);
    var __ret = __Internal.FPDFAnnotAddInkStroke(__arg0, __arg1, point_count);
    return __ret;
}

to

public static int FPDFAnnotAddInkStroke(global::PDFiumCore.FpdfAnnotationT annot, IntPtr points, ulong point_count)
{
    var __arg0 = annot is null ? __IntPtr.Zero : annot.__Instance;
    var __arg1 = points;
    var __ret = __Internal.FPDFAnnotAddInkStroke(__arg0, __arg1, point_count);
    return __ret;
}

and FPDFAnnotGetInkListPath from

public static uint FPDFAnnotGetInkListPath(global::PDFiumCore.FpdfAnnotationT annot, uint path_index, global::PDFiumCore.FS_POINTF_ buffer, uint length)
{
    var __arg0 = annot is null ? __IntPtr.Zero : annot.__Instance;
    var ____arg2 = buffer.__Instance;
    var __arg2 = new __IntPtr(&____arg2);
    var __ret = __Internal.FPDFAnnotGetInkListPath(__arg0, path_index, __arg2, length);
    return __ret;
}

to

public static uint FPDFAnnotGetInkListPath(global::PDFiumCore.FpdfAnnotationT annot, uint path_index, IntPtr buffer, uint length)
{
    var __arg0 = annot is null ? __IntPtr.Zero : annot.__Instance;
    var __arg2 = buffer;
    var __ret = __Internal.FPDFAnnotGetInkListPath(__arg0, path_index, __arg2, length);
    return __ret;
}

I can then read and write ink paths from my client code

// Read ink path
FS_POINTF_[] fs_points = new FS_POINTF_[pathSize];
unsafe
{
    fixed (FS_POINTF_* pointer = fs_points)
    {
        var ptr = (IntPtr)pointer;

        var count = fpdf_annot.FPDFAnnotGetInkListPath(pdfiumAnnot, (uint)inkIndex, ptr, pathSize);
    }
}

// Write ink path
unsafe
{
    fixed (FS_POINTF_* pointer = fs_points)
    {
        var ptr = (IntPtr)pointer;

        var count = fpdf_annot.FPDFAnnotAddInkStroke(annot, ptr, (ulong)Points.Count);
    }
}

Please advice on how to best add these patches to the generator so I can create a pull request.
