    • Handle viewport and scissor state changes for side-by-side framebuffers · 878c8b1e
      Martin Radev authored 
      Side-by-side framebuffers have viewport offsets as part of their state
which have to be applied to the viewport and scissor rectangles to
generate the final viewport and scissor rectangles of each view.
Whenever there is a transition to or from a side-by-side framebuffer,
viewport and scissor state has to be synced. Also, because rendering is
done on the same 2D texture the scissor test has to be always enabled to
guarantee that no fragments leak to a neighboring view.

The patch addresses this by extending the viewport and scissor state
in StateManagerGL to be a vector of rectangles instead of a single
rectangle. Two new dirty bits are added to cover changes in the viewport
offsets and whether the framebuffer has a side-by-side layout.

    • Disallow timer queries with multi-view draw framebuffers · ffe754b7
      Martin Radev authored 
      According to the ANGLE_multiview spec Draw* commands should generate
an INVALID_OPERATION error if there is an active query object for
target TIME_ELAPSED_EXT and the number of views in the active draw
framebuffer is greater than 1.

      According to the ANGLE_multiview spec, glReadPixels must generate an
INVALID_FRAMEBUFFER_OPERATION error if the active read framebuffer has

    • Fix BlitFramebuffer validation for BGRA sources and targets. · 17d27031
      Kenneth Russell authored 
      It is legal to blit between GL_RGBA8 and GL_BGRA8 sources and
destinations when resolving multisampled renderbuffers. Expand
BlitFramebuffer's validation to handle this case.

Work around a bug in macOS' OpenGL driver querying the number of
samples for GL_BGRA8.

Query GL_MAX_VERTEX_OUTPUT_COMPONENTS on the Core Profile to work
around an error generated on macOS when querying
GL_MAX_VARYING_COMPONENTS.

Expand the BlitFramebuffer tests to cover these cases and start
running them on the OpenGL backend.

    • Remove IndexRange in DrawElements functions · 1da00653
      Qin Jiajia authored 
      This change will remove IndexRange parameter in DrawElements functions.
And calculate it until we truly need it. Meanwhile we add direct
drawing path to avoid retrieving index range for DrawElements*
functions in D3D11 backend. This change may not bring much performance
improvement since we still need to retrieve index range in validation
at the beginning of every DrawElements* call entry point.
