In prop_sheet_proc you wrote:
    case PSN_APPLY:
        FIXME("(%p, %s, %s)\n", hwnd, "WM_NOTIFY", "PSN_APPLY");
        return TRUE;
If I understand it correctly applying changes is fully implemented. Why
there's a FIXME? Probably you wanted to use TRACE here.
        FIXME("(%p, %d, %ld, %p)\n", hwnd, msg, wparam, (void *)lparam);
There's lots of messages that your're not going to handle (e.g.
WM_SETCURSOR) so this FIXME will be very loud.

In pixels_to_dialog_units function:
You're using some hardcoded values here. Probably something like this
would be better, but I'm not sure if it's correct:
    static void pixels_to_dialog_units(short *x_pixels, short *y_pixels)
        int basey;
        float basex;
        HFONT font = GetStockObject(DEFAULT_GUI_FONT);
        HDC hdc = GetDC(NULL);
        TEXTMETRICW tm;
        SIZE size;

        font = SelectObject(hdc, font);
        GetTextMetricsW(hdc, &tm);
        GetTextExtentPoint32A(hdc, "ABCDEFGHIJKLMNOPQRSTUVWXYZ"
                "abcdefghijklmnopqrstuvwxyz", 52, &size);
        SelectObject(hdc, font);

        basex = ((float);
        basey = tm.tmHeight;

        *x_pixels = (float)(*x_pixels)*4/basex;
        *y_pixels = MulDiv(*y_pixels, 8, basey);
Of course the basex and basey values should be computed once.

In OleCreatePropertyFrameIndirect it's probably good to add a FIXME,
that dispidInitialProperty value is ignored.

Please try to use the same formatting in whole file (e.g. you sometimes
use white chars before brackets).
