Vulkan: glReadPixels should nearest sample the YUV render target Vulkan backend uses texture except texelFetch to obtain the YUV image value for glReadPixels. According to the chroma filter set in the image, it may apply LINEAR sampling. * Change this filter to NEAREST inside glReadPixels to get the correct pixel values. * Modify the fragment shader used in glReadPixels to make sure sampling from the center of the pixel. * Add a new end2end test.

ANGLE back-ends
This folder contains shared back-end-specific implementation files. The classes and types in
rendererare not specified by GLES. They instead are common to all the various ANGLE implementations.See
renderer_utils.hfor various cross back-end utilties.ANGLE Formats
The ANGLE format class,
angle::Format, works as a union between GLES and all the various back-end formats. It can represent any type of format in ANGLE. e.g. Formats in Vulkan that don’t exist in GLES, or DXGI formats that don’t exist in GLES, or Windows/Android surface configs that don’t exist anywhere else.The
glInternalFormatmember ofangle::Formatrepresents the “closest” GL format for an ANGLE format. For formats that don’t exist in GLES this will not be exactly what the format represents.The back-ends also define their own format tables. See the Vulkan Format table docs and the [D3D11 format table docs][D23D11FormatDocs].
DXGI Format Info
DXGI formats are used in both the GL and D3D11 back-end. Therefore the generated info table lives in this common shared location.
The DXGI info table is generated by
gen_dxgi_format_table.pyand sources data fromdxgi_format_data.json. The main purpose of the table is to convert from a DXGI format to an ANGLE format, where the ANGLE format should have all the necessary information.
