  13  This section describes all environment variables that affect execution of
  14  wxWidgets programs.

  20  @c WXTRACE
  21
  22
  23
  24
  25  (Debug build only.)
  26  This variable can be set to a comma-separated list of trace masks used in
  27  #wxLogTrace calls;
  28  wxLog::AddTraceMask is called for every mask
  29  in the list during wxWidgets initialization.

  39
  40  (Unix only.)
  41  Overrides installation prefix. Normally, the prefix
  42  is hard-coded and is the same as the value passed to @c configure via
  43  the @c --prefix switch when compiling the library (typically
  44  @c /usr/local or @c /usr). You can set WXPREFIX if you are for example
  45  distributing a binary version of an application and you don't know in advance
  46  where it will be installed.

  58  Sets MGL video mode. The value must be in form
  59  @e widthx@e height-@e depth. The default is @c 640x480-16.
