Line Cap- and Join Styles
=========================
DXF
---
The line cap- and join style is not stored in the DXF entities itself!
BricsCAD does not support the ENDCAPS and JOINSTYLE settings and always
uses round caps and round join style.
CTB files define line cap- and join styles:
- END_STYLE_BUTT = 0
- END_STYLE_SQUARE = 1
- END_STYLE_ROUND = 2
- END_STYLE_DIAMOND = 3 ???
- END_STYLE_OBJECT = 4
- JOIN_STYLE_MITER = 0
- JOIN_STYLE_BEVEL = 1
- JOIN_STYLE_ROUND = 2
- JOIN_STYLE_DIAMOND = 3 ???
- JOIN_STYLE_OBJECT = 5

$ENDCAPS: Lineweight endcaps setting for **new** objects:
- 0 = None (butt)
- 1 = Round
- 2 = Angle ???
- 3 = Square
$JOINSTYLE: Lineweight joint setting for **new** objects:
- 0 = None
- 1 = Round
- 2 = Angle (bevel or miter?)
- 3 = Flat (bevel or miter?)

Qt.PenJoinStyle:
- Qt.MiterJoin: The outer edges of the lines are extended to meet at an angle,
and this area is filled.
- Qt.BevelJoin: The triangular notch between the two lines is filled.
- Qt.RoundJoin: A circular arc between the two lines is filled.
- Qt.SvgMiterJoin: A miter join corresponding to the definition of a miter
join in the SVG 1.2 Tiny specification.
