Handle cases with fix dimensions. Fill spaces between boxes. Update tests

What cases are handled:
1) with center box
    a) left auto | center auto | right fix - use spec algorithm with
clause that dimensionAC is double max of left
max-content-dimension and right fix-dimension
    b) left fix | center auto | right fix - use spec algorithm with
clause that dimensionAC is double max of fix dimensions
    c) left auto | center fix | right auto - draw center box with
specified dimension value and split remain available space to
left and right boxes
    d) left auto | center fix | right fix - draw center and boxes with
specified dimension value and left remain available space to left
box (overlapping is possible)
    e) left fix | center fix | right fix - draw as is (overlapping is possible)
2) without center box
    a) left fix | right fix - draw as is (overlapping is possible)
