This field has no interpretation at the GrTexture/GrGpu as the orientation is
handled at the GrSurfaceProxy level.
This change requires GrGpu to accept a GrSurfaceOrigin when creating a texture with initial data. The origin refers to the texel data to be uploaded. Longer term the plan is to remove this and require the data to be kTopLeft. Additionally, kBottomLeft will only be allowed for wrapped texture/RTs as this evolves.

This fixes a bug on some intel devices where we are failing
in the ProcessorOptimizationTest.
I've tried other "no op" type things between the floor call and abs which
also fixed the issue, as well as adding explicit checks to see if we are
less than -1 or greater than 1 where the clamp is. Thus the clamp itself
should be a no op and shouldn't secretly be fixing the problem outside
of forcing the floor and abs lines to be separate.

Auto-allocated IDs mean that the IDs depend upon the order in which

The first phase of deferring GrPipeline creation until flush will apply only to GrDrawOp subclasses that do not derive from GrMeshDrawOp. This change prepares for that by creating separate draw functions on GrRenderTargetContext for GrMeshDrawOp-derived ops. This is temporary and will incrementally be undone as pipeline-creation deferral rolls out to the GrMeshDrawOps in a later phase of this work.
