wxWidgets: add patches to support KiCad

[mojca (Mojca Miklavec)]

KiCad (#47268) requires some patches of wxWidgets. Here's a list of ​patches for wxWidgets from the KiCad's ​build instructions:

in master

• ​wxwidgets-3.0.0_macosx_scrolledwindow.patch (include; also in 3.0 branch)
  • Some scrolling events
• ​wxwidgets-3.0.2_macosx_magnify_event.patch (include; not in 3.0 branch)
  • Adds support for a magnifying mouse gesture (possibly compare the patch with master)

not in master

• ​wxpython-3.0.0_macosx_multiarch.patch
  • Handles arch flags in build scripts, most likely not needed
• ​wxwidgets-3.0.0_macosx.patch and ​wxpython-3.0.0_macosx.patch
  • iI replaces carbon with cocoa at some places and fixes overlays (I don't completely understand it)
  • The patch for wxPython is slightly different from the patch for wxWidgets (why?)
  • Is there any ticket on the wxWidgets tracker about this issue?
• ​wxwidgets-3.0.0_macosx_bug_15908.patch
  • Some dirty patch to avoid crashes (I don't understand it, not sure what to do)
  • See also ​http://trac.wxwidgets.org/ticket/15908
• ​wxwidgets-3.0.0_macosx_soname.patch
  • It avoids running change-install-names
  • Similar patch was already in MacPorts in the past; see also ​http://trac.wxwidgets.org/ticket/15452
  • Most likely this is some weird practice of wxWidgets build system, but wxWidgets should work fine for us either with the patch or without
• ​wxwidgets-3.0.2_macosx_data_view_ctrl.patch
  • I don't understand it
• ​wxwidgets-3.0.2_macosx_retina_opengl.patch
  • Conflicting informations are circulating around about support of retina displays, so I'm a bit confused about why this is needed
  • See also ​https://forums.wxwidgets.org/viewtopic.php?t=36684
  • See also ​https://wiki.wxwidgets.org/WxMac-specific_topics#Retina_display_support
• ​wxwidgets-3.0.2_macosx_yosemite.patch
  • Why exactly is this needed and not included upstream?
  • Should the patch only be applied to Yosemite (and El Capitan) or to all versions?

And here's an ​alternative link with patches and build scripts.

See also #50768. It would make some sense to commit the changes together to avoid having to revbump and rebuild wxWidgets twice, even though digesting these changes might be slightly more complex than dealing with the other ticket.

I spoke to xzcvczx on #kicad, who said:

the yosemite one is needed on elcap and yosemite due to apple changing the webkit include but pre yosemite you can't change it obviously

data_view is not used can probably be scrapped

[mojca (Mojca Miklavec)]

Can you ask why the yosemite patch hasn't been fixed upstream? It should obviously contain an "if OS X >= 10.10", but it's a trivial one to apply.

ping! Any news here?

Close since now kicad is available on macports.
