This patch intends to implement all entry points related to Vertex Attrib Binding. (1) Add entry points and validation code on following APIs: - VertexAttribFormat - VertexAttribIFormat - VertexAttribBinding - BindVertexBuffer - VertexBindingDivisor (2) Add queries on following parameters: - VERTEX_ATTRIB_BINDING - VERTEX_ATTRIB_RELATIVE_OFFSET - VERTEX_BINDING_DIVISOR - VERTEX_BINDING_OFFSET - VERTEX_BINDING_STRIDE - VERTEX_BINDING_BUFFER BUG=angleproject:1593 TEST=angle_end2end_tests TEST=angle_unittests TEST=dEQP-GLES31.functional.state_query.integer.max_vertex_attrib_relative_offset_* TEST=dEQP-GLES31.functional.state_query.integer.max_vertex_attrib_bindings_* TEST=dEQP-GLES31.functional.state_query.integer.max_vertex_attrib_stride_* TEST=dEQP-GLES31.functional.state_query.vertex_attribute_binding.* TEST=dEQP-GLES31.functional.debug.negative_coverage.log.vertex_array.vertex_attrib_pointer TEST=dEQP-GLES31.functional.debug.negative_coverage.get_error.vertex_array.vertex_attrib_format TEST=dEQP-GLES31.functional.debug.negative_coverage.get_error.vertex_array.vertex_attrib_i_format Change-Id: I4b477a82df6aad89b89b088580a06d66963e6666 Reviewed-on: https://chromium-review.googlesource.com/446124 Commit-Queue: Corentin Wallez <cwallez@chromium.org> Reviewed-by: Corentin Wallez <cwallez@chromium.org>
