I have been looking at old test-cases for Canvas bugs which I discovered and submitted info on: such as Global Alpha, ArcTo, etc. Things seem to have been fixed, and it is very comforting to witness Mozilla developers having moved things forward over time. | I have been looking at old test-cases for Canvas bugs which I discovered and submitted info on: such as Global Alpha, ArcTo, etc. Things seem to have been fixed, and it is very comforting to witness Mozilla developers having moved things forward over time. | ||
There are other bugs/performance issues and features which need addressing. The lists that follow will have test cases added shortly and I will be trying to link these to old bugzilla reports so we can get some outstanding threads closed down. | There are other bugs/performance issues and features which need addressing.

== <br> '''Performance Issues:<br><br> ''' == | |||
<br> | '''A) Canvas Stalling''' - Canvas stalls with mouse movement, hardware interupts, CPU spikes etc and appears to stall at regular intervals when idle.<br> | ||

'''C) Slow Getting & Setting of Pixel Array''' - Currently pixels are being passed to a JS array. Some kind of abstraction is needed to act as an API to the JS developer, that while acting like an array. is really running at machine level.<br> | |||
