+/*
+ *
+ * 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));
+ *
