*** Original commit ***
Handle int instead of byte in SSIM.
The value of pixels are converted to integers at the point of use,
move this logic to the initialisation step.
This is a prerequisite step for testing SSIM calculation, which
will lead on to some SSIM improvements being verifiable.
Tested manually and SSIM values match for the same video
before and after this change.

Test that HDR editing succeeds on devices supporting HDR editing, tone maps on
devices supporting tone mapping, and throws exceptions on all other devices.
Also, only restrict HDR editing and tone mapping support to API 31+ only when
transcoding, not for all transformations.

shouldPassthrough's internal checks seem to be check whether we should *not*
pass through, which seemed a bit like a confusing double-negative to me.
shouldTranscode is slightly more clear, by instead returning true when we do
want to transcode.
No functional changes intended.

3b0d2c1586 made `shouldPassthrough` always return false for `enableHdrVideoEditing`:
>We force using `FrameEditor` (no passthrough) to avoid the need to select another edit operation, and use the new shaders. The `EGLContext` and `EGLSurface` also need to be set up differently for this path.
However, this was introduced before the `videoNeedsEncoding` setting was introduced in 3f615040c0. That setting should apply to HDR videos as much as SDR videos.

Upstream timestamps from the decoder are also in microseconds,

Adds a method to FrameProcessor.Listener to be called when an
output frame is available and a method releaseOutputFrame in
FrameProcessor allowing the caller to trigger release of the
oldest available output frame at a given timestamp. Late frames
or frames with unset release times are dropped in the
FinalMatrixTransformationProcessorWrapper.
More than one output frame can become available before they are
released if the penultimate GlTextureProcessor is capable of producing
multiple output frames. Processing continues while waiting for
releaseOutputFrame to be called. Frame release tasks are prioritized
over other tasks.

createSupportedTransformationRequest is more accurate than

Previously, this feature interpreted SDR signals as HDR when called. Now, only HDR
streams are interpreted as HDR, so the javadoc should be updated. Not yet removing
this method, as there are still some loose ends to finish up (ex. PQ support, e2e
tests).

While HDR is most closely tied to the color transfer (ex.
COLOR_TRANSFER_SDR is the only one explicitly mentioning dynamic
range), technically color spaces may be associated with HDR as well,
like BT.2020 commonly being used for HDR rather than BT.709 for SDR.
Therefore, it's more specific to mention just that the transfer is HDR.

Format.NO_VALUE is a placeholder value for an invalid @C.ColorTransfer, used
for example when the decoder doesn't support this transfer function.
When encountering this invalid value, interpret this as COLOR_TRANSFER_SDR.
Confirmed locally that an exception is thrown when transcoding on p4head, and no exception is thrown when transcoding with this CL.

TransformationException error codes were previously tied to OpenGL
but other FrameProcessor implementations are possible. So this CL
renames the error codes.
Also, remove GL_INIT_FAILED error code, as FrameProcessor
implemenations may initialize resources on a background thread
after the factory method returns, so it's not obvious how to
distinguish between initialization failures and processing failures.

This is needed for applying effects to a playlist.
The effects are applied based on the presentation time of the
frame in its corresponding media item and the offset is added
back before encoding.
Each time the offset changes, end of input stream is signalled
to the texture processors. This is needed because the texture
processors can expect monotonically increasing timestamp within
the same input stream but when the offset changes, the timstamps
jump back to 0.
