-// For Windows, Microsoft just hands you a list of preferred control sizes as part of the MSDN documentation and tells you to roll with it.
-// These sizes are given in "dialog units", which are independent of the font in use.
-// We need to convert these into standard pixels, which requires we get the device context of the OS window.
-// References:
-// - http://msdn.microsoft.com/en-us/library/ms645502%28VS.85%29.aspx - the calculation needed
-// - http://support.microsoft.com/kb/125681 - to get the base X and Y
-// (thanks to http://stackoverflow.com/questions/58620/default-button-size)
-// In my tests (see https://github.com/andlabs/windlgunits), the GetTextExtentPoint32() option for getting the base X produces much more accurate results than the tmAveCharWidth option when tested against the sample values given in http://msdn.microsoft.com/en-us/library/windows/desktop/dn742486.aspx#sizingandspacing, but can be off by a pixel in either direction (probably due to rounding errors).

-// div will not be 0 in the usages below
