[Lazarus] Control's default Height and AutoSize

[Gabor Boros]

Hi All,

I have three machines. One physical with Windows 10 (1703) and two 
virtual, one with Ubuntu Server 14.04.1 + KDE4 and Qt4 and one with RHEL 
7.5 + KDE4 and Qt4. Start a new project with trunk (57932), drop a TEdit 
on Form1 and change it's font to Droid Sans Mono Regular 10. With 
Windows the TEdit's original Height is 23, after font change 23 too. 
With Ubuntu 23 and 25, with RHEL 22 and 23. Why is the difference and 
what it's source?
