> You're absolutely right. When calculating, `GdipMeasureString` can likely complete the computation based solely on the parameters and the data recorded inside `graphics`. So, in essence, it could indeed uniformly use a temporary HDC to handle all scenarios. Should I modify the patch to uniformly use a temporary HDC in `GdipMeasureString`?
