Do not cache AVDs that are off screen
Bug: 128805564
Test: Manual + systrace; hwui_unit_tests; CtsUiRenderingTestCases
Only update a VectorDrawable's cache if it is onscreen. This fixes a
Twitter use case where the app has a ProgressBar that is exactly one
pixel offscreen. Prior to this CL, we repeatedly drew the ProgressBar's
AVD to a GPU surface, even though we clip it out later and never draw
that GPU surface. Now, we recognize that the AVD is outside of the
bounds of the screen, so we never draw to the GPU surface.
TreeInfo:
- store the size of the screen, retrieved from
CanvasContext::getNextFrameSize.
SkiaDisplayList:
- Store the matrix at the time of recording a VectorDrawable. Concat
that with the current matrix to determine whether the VD is on screen,
based on the TreeInfo. If it is offscreen, do not add it to the list
of AVDs that need to be updated ahead of rendering.
- In addition, if it is offscreen (or not dirty), do not call
setPropertyChangeWillBeConsumed(true). This prevents triggering
dispatchFrameCallbacks to update on the RenderThread when there is no
need to. This also mimics what would happen if the View/RenderNode had
been completely offscreen.
- Add a method to append an AVD to mVectorDrawables. Now that the vector
is of Pairs, this simplifies the call sites. Add a second helper to
just add an AVD without a matrix, for use in tests.
SkiaRecordingCanvas:
- get the current matrix and store it in the display list along with the
AVD.
CanvasContext:
- add getNextFrameSize, for reporting the size of the next frame without
dequeuing it
VectorDrawable.cpp:
- call quickReject to potentially short circuit drawing. This is for a
hypothetical use case (verified in a test app) where the containing
RenderNode is partially onscreen, but the AVD itself is not. Even
without the change to VectorDrawable.cpp, we skip uploading to the GPU
cache, the SkiaDisplayList still attempts to draw it. This change
keeps us from drawing it at all.
SkiaDisplayListTests.cpp:
- Now that I've hidden mVectorDrawables, call the new public APIs.
- prepareListAndChildren test
- for the clean VD, assert that getPropertyChangeWillBeConsumed
returns FALSE. This is due to the behavior change that we do not
set it unless the VD is dirty.
- set the bounds, so our onscreen check works.
- Add another test for prepareListAndChildren, which puts VDs offscreen.
