* main: Allow for the possibility of GL 3.2 without ARB_geometry_shader4.Paul Berry2013-08-011-1/+0
| | | | | | | | | | | | | | | | | | | | | | Previously, we assumed that the only way Mesa would expose geometry shader support was via the ARB_geometry_shader4 extension. But this extension has some extra complications over GL 3.2 (interactions with compatibility-only features, and link-time initialization of the constant gl_VerticesIn). So we want to allow for the possibility of supporting GL 3.2 (with GLSL 1.50 style geometry shaders) even if ctx->Extensions.ARB_geometry_shader4 is false. This patch adds a new function, _mesa_has_geometry_shaders(), which returns true if either ARB_geometry_shader4 is supported or the GL version is at least 3.2 desktop. Since compute_version() only enables GL 3.2 functionality when GLSL 1.50 support is present, a sufficient way for a back-end to advertise geometry shader support is to set ctx->Const.GLSLVersion >= 150. v2: Remove unnecessary ctx->Const.GeometryShaders150 constant.

* mesa: GL_ARB_shader_objects is not optionalIan Romanick2013-06-281-2/+0
| | | | | | | | | | | | | | This extension just provides some of the most basic software framework for GLSL. Without GL_ARB_vertex_shader or GL_ARB_fragment_shader, applications still cannot use GLSL. There's no value in conditionalizing support for this extension. NOTE: This has the side effect of enabling the extension in the radeon, r200, and nouveau drivers.
