Message : Fix baseVertex and baseInstance with streaming attributes baseInstance: Fixed by adding the intial offset to each copy for streaming attributes baseVertex: make sure mShaderConstants.onFirstVertexChange takes in correct firstVertex value for dynamic attribs (where firstVertex passed to StateManager11::updateState already include baseVertex) Bug: chromium:1078330, angleproject:3402 Change-Id: I289c4e3733fdf6f78af8c3adee84112c05a5abce Reviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/2227022 Reviewed-by: Jamie Madill <jmadill@chromium.org> Reviewed-by: Geoff Lang <geofflang@chromium.org> Commit-Queue: Shrek Shao <shrekshao@google.com>
