Add brief contribution instructions for Github users.

This should show up when opening Github pull requests.

git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@76688 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775
Rename tech notes to files with reasonable names.

Keep the old files to avoid breaking existing links to them, but just point to
the files in the new contributing subdirectory with more meaningful names now.

Also remove a couple of long obsolete tech notes.

git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@76689 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775
Convert contributors documentation to markdown.

The conversion is very superficial and there are probably many problems in the
Markdown rendering, but this is the first step towards making these documents
more readable when viewing them online.

git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@76690 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775
Update the README after recent changes.

Update the platform list after dropping Win9x and OS/2 support.

Use new URLs after web site redesign and Trac upgrade.

Added a brief version of README in markdown for Github users.

Now that we have CONTRIBUTING.md there doesn't seem to be any reason for not
having README.md as well.

Perhaps this one will replace docs/readme.txt in the future.

Fix wxDynamicLibrary compilation under Solaris.

Add const_cast<> needed for the call to dladdr() to compile.

git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@76694 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775
Allow using wxALIGN_CENTER in XRC for wxStaticText.

Only wxALIGN_CENTRE was allowed previously in the XRC, while both worked in
the code and also even in XRC but for wxSizer alignment.

git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@76695 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775
Compilation fix for wxFont in wxMotif.

Include wx/crt.h containing wxSscanf() declaration.

git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@76696 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775
Don't redefine _FORCENAMELESSUNION it if it is already defined. Fixes a warning when compiling with MinGW.

git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@76698 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775
Remove the unused anonymous function OffsetWindow to fix a compiler warning.

git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@76700 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775
Add a file with debug visualizers for MSVS 2013 and later.

For now this file contains just the visualizer for wxWindow which shows its
real (most derived) type as this is often the most useful thing you need to
know about the window.

git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@76701 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775
Add MSVS visualizers for wxArrayString, wxVector, wxWindowList.

Make viewing the contents of the (most common) container types easier when
debugging in MSVS 2012 or later.

Provide std::{vector,list}-like visualizers for wxVector and wxWindowList and
a special visualizer allowing to see the contents of wxArrayString in a
relatively common case when it has just or two elements.

git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@76702 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775
Remove the old release making instructions and scripts.

Using git-based scripts seems to work well and the old scripts are not
maintained any more and having several ways of making releases is just
confusing, so leave only one set of scripts, the one actually used since
2.9.

Display wxString in more readable way in MSVS debug visualizer.

Use "sb" format specifier to avoid having L"..." around the string and then
add just the quotes back manually.

git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@76711 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775
Make picker controls description in the manual less useless.

It's not really clear what potential benefit could library users extract from
the knowledge that the picker controls behaviour is "highly
platform-dependent".

Try to be flighty more helpful.

Add a page containing the screenshots of all controls to the manual.

It can be helpful to see all the controls at a glance, especially if you don't
know which control is needed.

git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@76713 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775
Under certain conditions, selecting a menu item triggers an assert in toplevel.cpp:1539:
 wxASSERT_MSG( m_menuDepth > 0, wxS("No open menus?") );

The conditions to reproduce:
- Windows 8.1
- An application manifest that indicates Windows 8.1 compatibility

In this case, wxGetWinVersion() used to return wxWinVersion_Unknown (Without a manifest indicating 8.1 support, wxWinVersion_8 is being returned). This in turn causes the version check against Windows98 in toplevel.cpp:450 to fail, ultimately leading to the mentioned assert.

See http://msdn.microsoft.com/en-us/library/windows/desktop/ms724439%28v=vs.85%29.aspx for details.

This patch on trunk adjusts adds the wxWinVersion_8_1 enum value and returns it on Windows 8.1 if the program is manifested as such.

In future, a different approach needs to be chosen that does not depend the deprecated GetVersion function.

Add a reminder to update the date on download page to release HOWTO.

This is probably useful as it was forgotten for 3.0.1.

git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@76718 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775
Clarify wxEVT_SLIDER event handler argument type in the documentation.

Unlike all other events generated by wxSlider, this one receives a
wxCommandEvent and not a wxScrollEvent.

Unfortunately @beginEventEmissionTable doesn't handle the case of a class
producing events of different types, perhaps it shouldn't be used at all here.

Handle WM_*MENU* events in wxWindow.

Contrary to MSDN implications, at least some of these messages are not
actually sent to the TLW for popup menus, but to the owning window or
even its parent window (!).

Move the handling of these events from wxTLW to wxWindow.  Move menu
depth tracking to wxFrame, because it only makes sense for frame's
menus and move DoGiveHelp() from wxTLW to wxFrame.
