Fix crash when creating distance field for large glyph
Do the multiplication of the normal components in floating point to avoid integer overflows. Also add an assert, since a scale of 0 here will cause a normal of (0, 0) which will assert further into the drawRectangle() function, and the cause is not immediately clear. Task-number: QTBUG-51956 Change-Id: If7187d56af28eaa149f8f362050a587da5adb262 Reviewed-by: Yoann Lopes <yoann.lopes@qt.io>
