How can you find the height of text on an HTML canvas?
The spec has a context.measureText(text) function that will tell you how much width it would require to print that text, but I can't find a way to find out how tall it is. I know it's based on the font, but I don't know to convert a font string to a text height.

Maximum size of a <canvas> element
I'm working with a canvas element with a height of 600 to 1000 pixels and a width of several tens or hundreds of thousands of pixels. However, after a certain number of pixels (obviously unknown), the canvas no longer display shapes I draw with JS. Does anyone know if there's a limit? Tested both in Chrome 12 and Firefox 4.
