GL content to Canvas 2d and vice versa is very slow
User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.31 (KHTML, like Gecko) Chrome/26.0.1410.64 Safari/537.31 Steps to reproduce: Copying data from/to 2d context to/from a webgl context. Example here: http://jsfiddle.net/zsmyK/9/ Actual results: Very slow performance on Firefox. Much worse than one chrome in certain cases (Chrome seems to 'remember' that a texture was already uploaded in the test case) Expected results: Since both canvas and webgl are on the gpu, copying data should be very fast.
