Colorbar placement overlaps sagittal slices in new test image

[hanayik]

The colorbar seems to be drawn on top of the last few rows of the sagittal slices in MP view.

Fix by changing line 547

drawColorbar(gl, [ltwh[0]+wX+margin, ltwh[1] + hY + margin, wY - margin - margin, hY * colorbarHeight]);

to read

drawColorbar(gl, [ltwh[0]+wX+margin, ltwh[1] + hZ + margin, wY - margin - margin, hY * colorbarHeight]);

The latest pull request demonstrates writing a multi-character string with descenders by writing the string Syzygy. You may want to delete that line, but if you maintain it, it should also be adjusted:

//demonstrate multi-character string with font descenders
drawTextBelow(gl, [ltwh[0]+wX + (0.5 * wY), ltwh[1] + hZ + margin + hY * colorbarHeight ], "Syzygy");
//draw colorbar (optional)
var margin = colorBarMargin * hY;
drawColorbar(gl, [ltwh[0]+wX+margin, ltwh[1] + hZ + margin, wY - margin - margin, hY * colorbarHeight]);
