    • Add support for timer queries in D3D11 · f04f6671
      Ian Ewell authored 
      Timer queries without context virtualization are now supported in the
Direct3D11 backend. Only the elapsed time portion of the GL extension is
supported though due to limitations of D3D11 preventing a reliable
implementation of the timestamp functionality. As a result of this, the
counter bits for the timestamp is set to 0 and any queries of the
timestamp will always return 0.

    • Implement EGL_experimental_present_path_angle · 6b3c1db5
      Austin Kinross authored 
      This allows ANGLE to render directly onto a D3D swapchain in the correct
orientation when using the D3D11 renderer.

The trick is to add an extra uniform to each shader which takes either
the value +1.0 or -1.0. When rendering to a texture, ANGLE sets this
value to -1.0. When rendering to the default framebuffer, ANGLE sets
this value to +1.0. ANGLE multiplies vertex positions by this value in
the VS to invert rendering when appropriate. It also corrects other
state (e.g. viewport/scissor rect) and shader built-in values
(e.g. gl_FragCoord).

This saves a substantial amount of GPU time and lowers power
consumption. For example, the old method (where ANGLE renders all
content onto an offscreen texture, and then copies/inverts this onto the
swapchain at eglSwapBuffers() time) uses about 20% of the GPU each frame
on a Lumia 630.

Verification:
+ dEQP GL ES2 tests pass when "present path fast" is enabled
+ all ANGLE_end2end_tests pass when "present path fast" is enabled
