The Gradient FX Pipeline.
The gradient overlay effect is a visual technique where a smooth color transition is applied over Game Objects, such as sprites or UI components. This effect is used to enhance visual appeal, emphasize depth, or create stylistic and atmospheric variations. It can also be utilized to convey information, such as representing progress or health status through color changes.
A Gradient effect is added to a Game Object via the FX component:
const sprite = this.add.sprite();
sprite.postFX.addGradient();

If no target
is specified, it will pop the framebuffer from the Renderers FBO stack
and use that instead, which should be done when you need to draw the final results of
this pipeline to the game canvas.
You can optionally set the shader to be used for the draw here, if this is a multi-shader
pipeline. By default currentShader
will be used. If you need to set a shader but not
a target, just pass null
as the target

The difference with this copy is that no resizing takes place. If the source
Render Target is larger than the target
then only a portion the same size as
the target
dimensions is copied across.
You can optionally set the brightness factor of the copy.

Called when the Game has fully booted and the Renderer has finished setting up.
By this stage all Game level systems are now in place. You can perform any final tasks that the pipeline may need, that relies on game systems such as the Texture Manager being ready.
This method is called once, when this Post FX Pipeline needs to be used.
Normally, pipelines will boot automatically, ready for instant-use, but Post FX Pipelines create quite a lot of internal resources, such as Render Targets, so they don't boot until they are told to do so by the Pipeline Manager, when an actual Game Object needs to use them.

Binds the source
Render Target and then copies a section of it to the target
Render Target.
This method is extremely fast because it uses gl.copyTexSubImage2D
and doesn't
require the use of any shaders. Remember the coordinates are given in standard WebGL format,
where x and y specify the lower-left corner of the section, not the top-left. Also, the
copy entirely replaces the contents of the target texture, no 'merging' or 'blending' takes
place.

Render Target.
This method does not bind a shader. It uses whatever shader is currently bound in this pipeline. It also does not clear the frame buffers after use. You should take care of both of these things if you call this method directly.

Pops the framebuffer from the renderers FBO stack and sets that as the active target,
then draws the source
Render Target to it. It then resets the renderer textures.
This should be done when you need to draw the final results of a pipeline to the game
canvas, or the next framebuffer in line on the FBO stack. You should only call this once
in the onDraw
handler and it should be the final thing called. Be careful not to call
this if you need to actually use the pipeline shader, instead of the copy shader. In
those cases, use the bindAndDraw
method.

By default this is an empty method hook that you can override and use in your own custom pipelines.
This method is called every time the Pipeline Manager makes this the active pipeline. It is called
at the end of the WebGLPipeline.bind
method, after the current shader has been set. The current
shader is passed to this hook.
For example, if a display list has 3 Sprites in it that all use the same pipeline, this hook will only be called for the first one, as the 2nd and 3rd Sprites do not cause the pipeline to be changed.
If you need to listen for that event instead, use the onBind
hook.

By default this is an empty method hook that you can override and use in your own custom pipelines.
This method is called immediately after this pipeline has finished flushing its batch.
It is called after the gl.drawArrays
call.
You can perform additional post-render effects, but be careful not to call flush
on this pipeline from within this method, or you'll cause an infinite loop.
To apply changes pre-render, see onBeforeFlush
.

By default this is an empty method hook that you can override and use in your own custom pipelines.
This method is called every time the batchQuad
or batchTri
methods are called. If this was
as a result of a Game Object, then the Game Object reference is passed to this hook too.
This hook is called after the quad (or tri) has been added to the batch, so you can safely call 'flush' from within this.
Note that Game Objects may call batchQuad
or batchTri
multiple times for a single draw,
for example the Graphics Game Object.

By default this is an empty method hook that you can override and use in your own custom pipelines.
This method is called every time a Game Object asks the Pipeline Manager to use this pipeline, even if the pipeline is already active.
Unlike the onActive
method, which is only called when the Pipeline Manager makes this pipeline
active, this hook is called for every Game Object that requests use of this pipeline, allowing you to
perform per-object set-up, such as loading shader uniform data.

This method is called once when this pipeline has finished being set-up at the end of the boot process. By the time this method is called, all of the shaders are ready and configured.
This method is only used by Sprite FX and Post FX Pipelines and those that extend from them.
This method is called every time the postBatch
method is called and is passed a
reference to the current render target.
At the very least a Post FX Pipeline should call this.bindAndDraw(renderTarget)
,
however, you can do as much additional processing as you like in this method if
you override it from within your own pipelines.

By default this is an empty method hook that you can override and use in your own custom pipelines.
This method is called once per frame, right before anything has been rendered, but after the canvas has been cleared. If this pipeline has a render target, it will also have been cleared by this point.
By default this is an empty method hook that you can override and use in your own custom pipelines.
This method is called when the Pipeline Manager needs to rebind this pipeline. This happens after a pipeline has been cleared, usually when passing control over to a 3rd party WebGL library, like Spine, and then returing to Phaser again.
By default this is an empty method hook that you can override and use in your own custom pipelines.
This method is called once per frame, by every Camera in a Scene that wants to render.

This method is called as a result of the WebGLPipeline.batchQuad
method, right after a quad
belonging to a Game Object has been added to the batch. When this is called, the
renderer has just performed a flush.
It calls the onDraw
hook followed by the onPostBatch
hook, which can be used to perform
additional Post FX Pipeline processing.
It is also called as part of the PipelineManager.postBatch
method when processing Post FX Pipelines.

This method is called as a result of the WebGLPipeline.batchQuad
method, right before a quad
belonging to a Game Object is about to be added to the batch. When this is called, the
renderer has just performed a flush. It will bind the current render target, if any are set
and finally call the onPreBatch
hook.
It is also called as part of the PipelineManager.preBatch
method when processing Post FX Pipelines.

Takes the given WebGLTextureWrapper and determines what to do with it.
If there is no current batch (i.e. after a flush) it will create a new batch from it.
If the texture is already bound, it will return the current texture unit.
If the texture already exists in the current batch, the unit gets reset to match it.
If the texture cannot be found in the current batch, and it supports multiple textures, it's added into the batch and the unit indexes are advanced.
