/* Important Note:
|
|
* These drawing functions clip draw item before send these items to wxDC draw
|
|
* functions. For guy who asks why i did it, see a sample of problems encountered
|
|
* when pixels
|
|
* coordinates overflow 16 bits values:
|
|
* http://trac.wxwidgets.org/ticket/10446
|
|
* Problems can be found under Windows **and** Linux (mainly when drawing arcs)
|
|
* (mainly at low zoom values (2, 1 or 0.5), in pcbnew)
|
|
* some of these problems could be now fixed in recent distributions.
|
|
*
|
|
* Currently (feb 2009) there are overflow problems when drawing solid (filled)
|
|
* polygons under linux without clipping
|
|
*
|
|
* So before removing clipping functions, be aware these bug (they are not in
|
|
* kicad or wxWidgets) are fixed by testing how are drawn complex lines arcs
|
|
* and solid polygons under Windows and Linux and remember users can have old
|
|
* versions with bugs
