Fix not using texture barrier on StrokeTessOp.
|
|
|
|
Previously we were overwriting the renderpassXferBarriers flag on
|
|
ProgramInfo to set it to kNone. This flag is meant to say whether or not
|
|
the entire render pass uses barriers or not. This is needed in Vulkan
|
|
because all pipelines in a render pass that has an input attachment
|
|
must bind the input attachment regardless if it is used or not. So the
|
|
pipeline must be created with a layout for an input attachment
|
|
descriptor set.
|
|
|
|
This change just removes to performance optimization to only use the
|
|
barrier on the stencil and not fill draw. This use case shouldn't
|
|
come up too often and also shouldn't be a big perf hit regardless.
|
|
The way GrAppliedClip is created/used it is hard for us to create
|
|
multiple different Pipeline objects: one for stencil and one for the
|
|
fill.
