The existing logic was not working sometimes because:
1. The repeated scheduling in releaseAllFramesFromMediaCodec was
starving the thread on which the SurfaceTexture frameAvailableListener
was called.
2. The case where a pending frame arrives on the surface after flush
finishes executing was not handled.
The consequence of both problems is that availableFrameCount ended up
being > pendingFrames.size().

OpenGL ES 3.0 likely can be used since Android 18.
Moving to a higher version context more often can make
sharing GL context easier for apps

* Changes to GlUtil to manage Pixel Buffer Objects and asynchronous
GPU -> CPU glReadPixels
* Make ByteBufferConcurrentEffect non-blocking
PiperOrigin-RevId: 667908805
* new ByteBufferGlEffect GlEffect that enables API users to
implement an effect that accesses video frame data via CPU-mapped ByteBuffer
* ByteBufferConcurrentEffect responsible for reading
video frame data in CPU-accessible ByteBuffer

Implement a QueuingGlShaderProgram which queues up OpenGL frames and allows
asynchronous execution of effects that operate on video frames without a
performance penalty.

Previously in MultiInputVideoGraph, each VFP would destroy the shared
eglContext, such that the same eglContext object is destroyed multiple times.
Adding a flag to disallow this.
The alternative being we could add a flag on the VFP constructor, but I think
that is too subscriptive (meaning if we later might want to add another boolean
to control another GL behaviour, multiple booleans would make the class less
reason-able), and would incur a lot of code changes at places.

Transformer.experimentalSetMaxFramesInEncoder controls max number
of frames in encoder.
VideoFrameProcessor now allows delayed releasing of frames to Surface,
while still using the original presentation time.
VideoSampleExporter can now configure video graphs to not render frames
automatically to output surface.
VideoSampleExporter.VideoGraphWrapper tracks how many frames are ready
to be rendered to Surface, and how many frames are already in-use by encoder.

Public methods either assert they're running GL thread, or
submit a task to run on GL thread.
Move methods to keep interface implementations together.
Add javadoc to VideoFrameProcessingTaskExecutor to clarify which
thread can call each public method.

Build upon Transformer.videoFrameProcessorFactory in MultipleInputVideoGraph
Check that Transformer.videoFrameProcessorFactory is DefaultVideoFrameProcessor
for multi-input video

eglDestroySurface only destroys the surface when it's made not current.
Pass the placeholder surface in FinalShaderProgramWrapper and use it
when destroying eglSurface.
PiperOrigin-RevId: 655139661
Add VideoFrameProcessingTaskExecutor.invoke() method that blocks until
Task has executed on GL thread.
Use that for FinalShaderProgramWrapper.setOutputSurfaceInfo

This is because the force EOS workaround for videos is longer than the original
muxer timeout. This way the apps depending on Transformer won't have to manually
set the muxer timeout on emulators.

Deprecate `setInputDefaultBufferSize` and `setRequireRegisteringAllInputFrames`
as the new input stream type replaces these (as far as we know they are always
used together).
This is in preparation for supporting asset loaders signaling that they require
these features, specifically for recording from a surface.

Previously, if renderFramesAutomatically = false, DefaultVideoFrameProcessor
may call onInputStreamProcessedListener after all frames have been
onOutputFrameAvailableForRendering, but before they had all been rendered and
freed.
Delay onInputStreamProcessedListener being called and subsequent DVFP
reconfiguration of effects, until all frames are rendered.
Tested using exoplayer setVideoEffects demo with playlist

useHdr is unused option and doesn't make sense is the dynamic range of the overlay and video must match

Avoid scaling the lanczos windown function when scaling up.
When scaling up (output > input), we shouldn't scale the window
function or we risk not sampling any of the input pixels.
PiperOrigin-RevId: 641838149
Add SeparableConvolution.configure(inputSize) to allow effect configuration
depending on input dimensions.
Add LanczosResample.scaleToFit method to scale input images to fit inside
given dimensions.

fragment_shader_separable_convolution_es2.glsl had optimizations that assumed
all convolution coefficients are positive. Support negative coefficients,
and add tests.

Switch from 4-channel RGBA_16F lookup texture to 1-channel R_16F.
Do not use a bitmap when creating the lookup table texture.
Instead, fill the texture directly.
Do not manually convert 32-bit float to 16-bit. Instead, let OpenGL
libraries do this for us.
PiperOrigin-RevId: 639717235
Add DefaultVideosFrameProcessor experimental flag that controls
whether input Bitmaps are sampled once for a repeating sequence of
output frames with the same contents, or once for each output frame.
PiperOrigin-RevId: 637921350
Only sample from input bitmap when the input image has changed.
Introduce GainmapShaderProgram.newImmutableBitmap API that signals
input bitmap changes to GainmapShaderProgram (DefaultShaderProgram).

Before this CL, externalShaderProgramInputCapacity was not reset when
the external shader program was reset (which occurs when the
InputSwitcher switches to an input with a different ColorInfo). This is
due to a regression introduced in bef3d518d2.

PQ and HLG have different luminance ranges (max 10k nits and max 1k nits resp). In GL, colors work in a normalised 0 to 1 scale, so for PQ content, 1=10k nits and and for HLG content, 1=1k nits.
This cl scales and normalises PQ content appropriately so that all HDR content works in the HLG luminance range. This fixes two things
1. Conversions between HLG and PQ are "fixed" (before the output colors looked too bright or too dark depending on which way you are converting)
2. color-altering effects will be able to work consistently across HLG and PQ content
1 is tested in this cl. 2 will be tested when ultra HDR overlays are implemented, both cases have been manually tested to ensure the output looks correct on a screen.

Fragment shaders in OpenGL ES shader language aren't guaranteed
to support highp, required to correctly represent pixel coordinates
inside large images (e.g. 1920x1080).
This change moves coordinate mirroring for images out of fragment shader.
