Controls arrangement inside the Control Panel (Settings window)

[FlorinTulba]

Problems:

1. the Control Panel allocates lots of space to sliders, while squeezing many buttons within certain rows
2. the labels of the sliders are truncated

Causes: The Control Panel is part of the GUI-support provided by the 'highgui' library from OpenCV. The requirements from the application are met by this library, which has, however, some limitations:

• the rows of buttons from the Control Panel must be (vertically) separated by at least 1 slider, that is 2 consecutive buttons can't be placed on consecutive rows - they will always be grouped on the same row. To form a new row (group) of buttons, at least 1 slider must be inserted before the new buttons
• each slider occupies an entire row and the label dimension cannot be controlled

Solutions:

1. permute the controls to insert slider(s) between buttons which need to stay on separate rows
2. click the labels to see the whole untruncated text of the label

Unless using a different GUI-engine, this is a tolerated issue.
