[patch][cla] _maskUtils does not properly create SVG mask when specifying left and right borders for the mask

[Sebastien Brunot]

Reproduced with Firefox 24.5.0 ESR on Mac OS X 10.9.

When displaying the included test page test_maskUtils.html on a non webkit browser that supports SVG, the mask is not correct.

See the attached screenshots: safari.tiff shows how the mask is correctly displayed in Safari, firefox.tiff shows how the mask is wrongly displayed in firefox.

The issue can be fixed by updating _maskUtils.js createRoundMask function as following:

// Fix for this ticket
if (l > 0) {
    d += " M0,0 h" + l + " v" + th + " h" + (-l) + " z";
}
if (r > 0) {
    d += " M" + (l + w) + ",0 h" + (r) + " v" + th + " h" + (-r) + " z";
}
// End of fix for this ticket
if (t > 0) {
    d += " M0,0 h" + tw + " v" + t + " h" + (-tw) + " z";
}
if (b > 0) {
    d += " M0," + (t + h) + " h" + tw + " v" + b + " h" + (-tw) + " z";
}
