Elias Naur 97299dc2f9 op/paint: make every ImageOp unique ...

The gioui.org/commit/74407a50d598bfd27e8f8e48b6832cc5df04de77
added a NewImageOp constructor that always copies the supplied
image. It does that for two reasons:

First, the image.Image reference is used in the image=>texture
map of cached textures. Without a copy, we wouldn't detect a
modified image even if a new ImageOp was created.

Second, we don't want the program to touch the image while the GPU
is uploading it.

The second reason was removed in a previous change that blocks
FrameEvent.Frame until we're done with the operations, including
uploading images to the GPU.

The first reason is easily fixed by using a unique per ImageOp,
as pointed out by Alessandro Arzilli.

This change switches to using the unique key. Alessandro's patch
avoids the copy when possible.
