We'll restore this code and finish it up for the next release.
For now, removing this code restores parity with the 3.0 beta,
i.e. face-varying patches are always all bilinear.
There's a lot of good foundational work here to eventually support
smooth interpolation of face-varying patches. Unfortunately, this
is not quite ready to release. Therefore, we've decided to defer this
feature until a later release.
This change hides this code behind the FAR_FVAR_SMOOTH_PATCH macro.
Now the channel specifier is the last parameter in a method's
parameter list with a default of 0. This is consistent with the
topological face-varying queries and also simplifies the common
case of just a single face-varying channel.
As a preparation for retiring DrawContext, move SupportsAdaptiveTessellation
method to examples/common/glUtils, which is renamed and namespaced
from gl_common.{cpp,h} to be consistent to other files.
Same renamings applied to other example files.
