Tessellation partial implementation (not ready for use yet), including:
- the built-in constants - built-in variable declarations, some dependent on gl_MaxPatchVertices - layout qualifier for vertices (shared with geometry shader max_vertices) - layout qualifiers for vertex spacing, vertex order, point mode, and primitive type - link semantics for layout qualifiers Still TBD: - patch qualifier and arrayed input handling - sizing of gl_out[] - additional semantic checking - supporting the extension on version 150 git-svn-id: https://cvs.khronos.org/svn/repos/ogl/trunk/ecosystem/public/sdk/tools/glslang@24468 e7fa87d3-cd2b-0410-9028-fcbf551c1848
