This D3D-only class has one method, used to generate the D3D
IndexBuffer/VertexBuffer. This can help us mock up
IndexDataManager.

At a later point we can refactor the VertexFormat queries
from Renderer into a Caps struct that mirrors our Texure
Caps.

ESSL 1.00 spec section 4.1.7 says that structs containing samplers can't

Make sure that the computed index range is added to the cache of the main
buffer object, instead of just to the static buffer object created for the
buffer object. This applies to the code path used for D3D9. This way the
front-end code in ValidateDrawElements gets the index range from the cache
instead of having to iterate over all the indices used on every draw call.

We integrate dEQP as a console application and a shared library which
runs all of the test logic. Using a shared library lets us compile
dEQP with all the specific compiler options it needs, without
conflicting with the compile settings in ANGLE proper.

Currently we only support Windows D3D11, ES 2 and 3. We can add
other targets in the future.

We also have a few bugs preventing us from running the test suite in
full. We run into infinite loop problems in some shader tests, and
have crashes or UNIMPLEMENTED in others.
