Problem with commit "Improved StatusbarProgressDidget that looks better on OS X and Linux"

[Anton Anikin]

Hi, René.

Thanks for you work with KDevelop code. 

I have have small UI problem on my linux system (Arch) with your last commit: 
when progress bar is shown, the height of bottom dock bar is changes 
(increases), and when progress is closed height decreases back. Such "jumps" 
is annoying :(

Video demo: https://cloud.htower.ru/s/qvbCfNNjz8uvI91

I found the problem in StatusbarProgressWidget::StatusbarProgressWidget(), 
file line 116: 

iconSize.scale( maximumHeight - 2, maximumHeight - 2, Qt::KeepAspectRatio );

If the line is commented then dock bar resizing is not happens. Can you find 
more accurate ("right way") solution for this problem?

Thanks.
