 /*
  *
  * This file is #included directly by gfxFontSelectionTest.cpp, and as
  * such does not need any #include files or similar.  (However, should
  * any extra ones be required, it should be ok to do so, as well as
  * defining new functions, etc.
  *
  * To add a new test, call AddTest with the following arguments: the
  * CSS font-family string, the gfxFontStyle, an enum (either S_ASCII
  * or S_UTF8) indicating the string type, and then the text string
  * itself as a string literal.  Unfortunately there is no good way to
  * embed UTF8 directly into C code, so hex literals will need to be
  * placed in the string.  Because of the way \x is parsed things like
  * "\xabcd" won't work -- you have to do "\xab""cd".  "\xab\x01\x03"
  * will work fine, though.
  *
  * The result of AddTest should be assigned to the variable t; after
  * AddTest, one or more calls to t->Expect() should be added to define
  * the expected result.  Multiple Expect() calls in a row for the same
  * platform mean that the resulting glyph/font selection items needs
  * to have as many items as there are Expect() calls.  (See below for
  * examples.)
  *
  * The arguments to Expect are:
  *
  *   platform - a string identifying the platform.
  *      Valid strings are "win32", "macosx", and "gtk2-pango".
  *   font - a string (UTF8) giving the unique name of the font.
  *      See below for how the unique name is constructed.
  *   glyphs - a set of glyph IDs that are expected.
  *      This array is constructed using a GLYPHS() macro.
  *
  * GLYPHS() is just a #define for LiteralArray, which is defined
  * in gfxFontSelectionTest.cpp -- if you need more array elements
  * than available, just extend LiteralArray with a new constructor
  * with the required number of unsigned longs.
  *
  * The unique font name is a platform-specific constructed string for
  * (mostly) identifying a font.  On Mac, it's created by taking the
  * Postscript name of the font.  On Windows, it's created by taking
  * the family name, and then appending attributes such as ":Bold",
  * ":Italic", etc.
  *
  * The easiest way to create a test is to add a call to AddTest, and
  * then run the test.  The output will include a list like:
  *
  * ==== Test 1
  *  expected:
  * Run[ 0]: 'Verdana' 73 82 82
  * Run[ 1]: 'MS UI Gothic' 19401
  * Run[ 2]: 'Verdana' 69 68 85
  * Test 1 failed
  *
  * This gives you the information needed for the calls to Expect() --
  * the unique name, and the glyphs.  Appropriate calls to expect for
  * the above would be:
  *
  *   t->Expect ("win32", "Verdana", GLYPHS(73, 82, 82));
  *   t->Expect ("win32", "MS UI Gothic", GLYPHS(19401));
  *   t->Expect ("win32", "Verdana", GLYPHS(69, 68, 85));
  *
