Before the refactor library browser display Bezier curves correctly only
once, at other times they were just straight lines or crashed the
application.
Removes the need of using the legacy code in polygon/PolyLine.{h,cpp},
refactoring all CPolyLine instances with SHAPE_POLY_SET instances.
The remaining legacy methods have been ported to SHAPE_POLY_SET;
mainly: Chamfer, Fillet, {,Un}Hatch.
The iteration over the polygon vertices have been simplified using the
family of ITERATOR classes.
* CPolyLine::Chamfer (and CPolyLine::Fillet) : removes null segments before calculating modified outlines.
It fixes some incorrect outlines after chamfer or fillet due to null segments creating overflow during calculations.
* CPolyLine::Chamfer : code cleaning (avoid useless double to integer and integer to double conversions).
In polygon calculations (combining polygons, fracture) the mode of calculation (fast or strictly simple polygon option) as no more a default value, because choosing the best mode is better to optimize the calculation time.
Previously, acute angles (especially small angles) in zone outlines create incorrect shapes and sometimes strange shapes for clearance areas, when using generic algorithms.
This happens when zones outlines have "spikes", but not usually for smooth outlines.
2) Change from legacy Cu stack to counting down from top=(F_Cu or 0).
The old Cu stack required knowing the count of Cu layers to make
sense of the layer number when converting to many exported file types.
The new Cu stack is more commonly used, although ours still gives
B_Cu a fixed number.
3) Introduce class LSET and enum LAYER_ID.
4) Change *.kicad_pcb file format version to 4 from 3.
5) Change fixed names Inner1_Cu-Inner14_Cu to In1_Cu-In30_Cu and their
meanings are typically flipped.
6) Moved the #define LAYER_N_* stuff into legacy_plugin.cpp where they
can die a quiet death, and switch to enum LAYER_ID symbols throughout.
7) Removed the LEGACY_PLUGIN::Save() and FootprintSave() functions.
You will need to convert to the format immediately, *.kicad_pcb and
*.kicad_mod (=pretty) since legacy format was never going to know
about 32 Cu layers and additional technical layers and the reversed Cu
stack.
This workaround was already used (bzr 4301, in file plot_board_layers.cpp) also to avoid similar crashes (uses 18 segments instead of 16 to approximate a circle by segments).
Minor code cleanup in dialog_plot.
1. block created from-left-to-right selects only 100%inside selection objects (as it now does)
2.block created from-right-to-left selects all overlapping objects inside selection
From the patch sent by mathieulj (mathieulj), and some fixes and code cleaning.
- Removed spurious int casts (these are truncated anyway and will break
doubles)
- Applied the Distance, GetLineLength, EuclideanNorm, DEG2RAD, RAD2DEG
ArcTangente and NORMALIZE* functions where possible
- ArcTangente now returns double and handles the 0,0 case like atan2, so
it's no longer necessary to check for it before calling
- Small functions in trigo moved as inline
the spurious warning about stuff that couldn't be seen when changing
colours.
NOTE that the 'net name' layer is present and configurable but non used
anywhere!
