OS/Version: Mac OS X 10.5

SVGTextElement.getRotationOfChar() fails (Acid3 bug)
Test 79: expected 90, got: 0 - getRotationOfChar(0) failed.
function () {
// test 79: SVG textPath and getRotationOfChar(), from Erik Dahlstrom
//
// The getRotationOfChar[4] method fetches the midpoint rotation
// of a glyph defined by a character (in this testcase there is
// a simple 1:1 correspondence between the two). The path is
// defined in the empty.svg file, and consists of first a line
// going down, then followed by a line that has a 45 degree
// slope and then followed by a horizontal line. The length of
// each path segment have been paired with the advance of each
// glyph, so that each glyph will be on each of the three
// different path segments (see text on a path layout rules[5]).
// Thus the rotation of the first glyph is 90 degrees, the
// second 45 degrees and the third 0 degrees.
