+ Add gl_FragDepth layout qualifiers to communicate what kind of changes will be made to gl_FragDepth (GL_AMD_conservative depth).
|
||||
+ Add C-style curly brace initializer lists syntax for initializers. Full initialization of aggregates is required when these are used.
|
||||
+ Allow .length() to be applied to vectors and matrices, returning the number of components or columns.
|
||||
+ Clarify that .length() returns an int type and can be used as a constant integer expression.
