Don't pass logs at unknown levels to wxLog::DoLogRecord() from wxLogGui.
This results in an assert in DoLogText() which is not implemented in the base
class but ends up being called as DoLogTextAtLevel() doesn't know how to
handle non-standard log levels otherwise. This assert happened if you simply
called wxLogMessage(wxLOG_User, ...) in the program.
Just ignore messages at unknown log levels instead in wxLogGui, by definition
it can't handle them anyhow.

Fixed dialog units <-> pixels conversion.
The computation is now identical to Windows native one. To achieve this,
MSDN-recommended GetTextExtent() call is used instead of GetCharWidth().
wxMulDivInt32() is used instead of integer arithmetics to achieve
correct rounding.
Use toplevel parent's font instead of window's own. This makes more
sense, as dialog units are defined for TLWs, not individual subcontrols.
Also fixed wxMSW's wxButton::GetDefaultSize() to compute dialog units

Correct bug with returning 0 for non-empty input from wxConvAuto::ToWChar().
Since the changes of r63064 we could return 0 when asked to convert a

Check the result of ToWChar() call in wxTextInputStream::NextChar() better.
The logic in this function depends on ToWChar() working correctly so check
that it doesn't return obviously wrong results, e.g. 0 output length for
non-empty input. This was mostly done to detect the problem in wxConvAuto
currently but it could also be useful with user-defined conversions and
shouldn't have a big performance effect on wxTextInputStream so leave these
checks in to facilitate debugging in the future.

Replace wxLogWarning()s in wxOSX wxComboBox code with asserts.
This incidentally fixes compilation when not using PCH as wx/log.h was not
included but is also more correct as the messages meant for the programmer,

Also correct some asserts messages. In particular, don't mention the function
name in the message itself as it's already shown by the assert and using it in
the string itself isn't useful and simply introduces the risk of forgetting to
update it after refactoring, as happened here in r63105.

Allow to not create wxPaintDC in EVT_PAINT handler in wxMSW.
Failure to create a wxPaintDC in EVT_PAINT handler resulted in many serious

shouldn't do it but this wasn't enough (see #11648). We could also assert if
we detected that a handler didn't create a wxPaintDC but it seems better to
just handle this case gracefully for consistency with the other platforms.
Add wxDidCreatePaintDC global variable which is reset before generating
wxPaintEvent and set to true when ::BeginPaint() is called from wxPaintDC
ctor and validate the update region of the window ourselves if it wasn't set
(meaning that wxPaintDC wasn't created).

wxPaintDC but without saying that wxPaintDC object must always be created in
the handler as this is not true any more.

Correct this by simply checking if the parent rectangle intersects the visible

Only disable use of non-ANSI functions in strict ANSI mode under Windows.
The changes of r62518 fixed compilation of wx headers in g++ strict ANSI mode
(enabled by th use of -ansi or -std=c++{98,0x} options) with mingw32 but
broke it when using g++ in ANSI mode under Unix. The problems arose at least
due to redeclaration of isascii() with different exception specifier and due
to the lack of wxCRT_StrdupA() definition in the library.
Fix this by simply not disabling the use of non-ANSI functions such as
isascii() and strdup() under Unix as they are still available in the headers
by default because of _GNU_SOURCE predefined by g++.
Notice that if _GNU_SOURCE is explicitly undefined, compilation would probably
still be broken. To fix this we might check whether __USE_SVID is defined
under Linux. Unfortunately doing tests in configure is not an answer as
wxWidgets might not be compiled with the same -std option as the programs
using it, so there is no obviously correct way to fix this.
