This is still not a final solution. I would like to see buttonhandling in
own class for better integration and handling of window structure.

use this fucntion for painting icons with captions in horizontal or vertical direction.
* x set horizontal startposition
* y set vertical startposition
* footerwidth set width of buttonbar as similar to footer, value 0 (default) means: do nothing, then paint it extra
* count set count of buttons
* content set struct buttonlabel with iconfile and locales, for an empty text let locale constant empty, so you can paint icons without captions,
* width width of footer, contains the buttons
* footerheigth set height of buttonbar as similar to footer, value 0 (default) means: value calculates automaticly depends of maximal height of icon and caption
* buttonwidth set width of buttonlabel include icon, caption and offsets, value 0 (default), calculates automaticly the buttonwidth, buttons will be paint like a chain
* vertical_paint optional, default value is false (horizontal) sets direction of painted buttons
* fcolor optional, default value is COL_INFOBAR_SHADOW, use it to render font with other color
* alt_buttontext optional, default NULL, overwrites button caption at definied buttonlabel id (see parameter alt_buttontext_id) with this text
* alt_buttontext_id optional, default 0, means id from buttonlable struct which text you will change
