fix mutating *image.RGBA when converting PictureDataFromImage

The initializer is surprisingly expensive.
...
Removing the call to Alpha(1) and replacing it with an inline definition
produces measurable improvements. Replacing each instance of ZV with
Vec{} further improves things. We keep an inline RGBA because there
are circumstances (mostly when using pictures) where we don't want to
have to set colors to get default behavior.
For a fairly triangle-heavy thing, this reduces time spent in SetLen
from something over 10% of execution time to around 2.5% of execution
time.
