#2 perhaps "Set single component for pixel" and  "each component can be
independently set." are not clear?

as I understand it putImageData() requires alpha and RGB color to be set for
each pixel.

this bug proposes that a single component such as alpha might be set.
and thus not requiring the other three components to be set (again) at the same

the issue is that where only one of the four is being manipulated processing
time could be accelerated, on large full screen images of many megabytes.

apologies if I misunderstand the situation.
