Allow support for rotated type

[GoogleCodeExporter]

The Pear modification of the FPDF library includes a routine called 
writeRotated().
I'm not sure if it will support any angle, but from the looks of it, it should.

I'm working on converting this, but since I haven't done too much with the 
source
yet, I'm not exactly sure how it is going to work out. If anyone else would 
like to
give it a shot, here's the method:

    function writeRotated($x, $y, $text, $text_angle, $font_angle = 0)
    {
        if ($x < 0) {
            $x += $this->w;
        }
        if ($y < 0) {
            $y += $this->h;
        }

        /* Escape text. */
        $text = $this->_escape($text);

        $font_angle += 90 + $text_angle;
        $text_angle *= M_PI / 180;
        $font_angle *= M_PI / 180;

        $text_dx = cos($text_angle);
        $text_dy = sin($text_angle);
        $font_dx = cos($font_angle);
        $font_dy = sin($font_angle);

        $s= sprintf('BT %.2' . FILE_PDF_FLOAT . ' %.2' . FILE_PDF_FLOAT . ' %.2' .
FILE_PDF_FLOAT . ' %.2' . FILE_PDF_FLOAT . ' %.2' . FILE_PDF_FLOAT . ' %.2' .
FILE_PDF_FLOAT . ' Tm (%s) Tj ET',
                    $text_dx, $text_dy, $font_dx, $font_dy,
                    $x * $this->_scale, ($this->h-$y) * $this->_scale, $text);

        if ($this->_draw_color) {
            $s = 'q ' . $this->_draw_color . ' ' . $s . ' Q';
        }
        $this->_out($s);
    }

Hi bustback,

I have added a rotate method which is accepting a matrix. I will call it
transparently for all the different drawing methodds (addImage, addCell, 
addText, etc).

Give me a few days and I'll post an update ;)

Thanks !
