Certain effects produce invalid alpha values #719

Description of the bug
Related: #706 (reply in thread)
BloomEffect and TextureEffect currently produce incorrect alpha values in v6 and v7.
The output should be max(inputColor.a, texel.a). Otherwise, the blurred colors end up having 0 alpha which is invalid.

Correct color results.
