[Skia] Add initial support for accelerated filters
https://bugs.webkit.org/show_bug.cgi?id=272535
Reviewed by Carlos Garcia Campos.
This changeset enables accelerated filters on Skia builds.
Make WebCore::Page report FilterRenderingMode::Accelerated on Skia
builds if accelerated compositing is enabled.
Create Skia filters both in accelerated and software-based code paths,
since Skia is able to handle unaccelerated buffers transparently.
Add Skia-specific code to WebCore::FilterImage. The idea is that Skia
filters acquire a SkCanvas with WebCore::FilterImage::beginRecording(),
render the source image however they want, and finish the operation with
WebCore::FilterImage::finishRecording(). This generates a SkPicture
which is then used to paint on the resulting image buffer.
The memory cost is estimated using SkPicture. It's not an accurate
measure though.
Implement 3 filters as an exercise of usage of this new code:
* SourceGraphicSkiaApplier, which merely copies the source image
* FEColorMatrixSkiaApplier, for CSS and SVG filters like saturate(),
greyscale(), contrast(), and others
* FEGaussianBlurSkiaApplier, for the blur() filter
More filters will be added in follow up commits, as needed.
