mesa: fix transform feedback when a geometry shader is active.
When a geometry shader is active, the transform feedback primitive type ("mode") needs to be validated against the geometry shader output primitive type, not the primitive type passed to the glDraw*() function. Fixes the following piglit tests: - glsl-1.50-geometry-primitive-types GL_LINES - glsl-1.50-geometry-primitive-types GL_LINES_ADJACENCY - glsl-1.50-geometry-primitive-types GL_LINE_STRIP - glsl-1.50-geometry-primitive-types GL_LINE_STRIP_ADJACENCY - glsl-1.50-geometry-primitive-types GL_TRIANGLES - glsl-1.50-geometry-primitive-types GL_TRIANGLES_ADJACENCY - glsl-1.50-geometry-primitive-types GL_TRIANGLE_FAN Exposes previously hidden failures in the following piglit tests: - glsl-1.50-geometry-primitive-id-restart GL_LINES other - glsl-1.50-geometry-primitive-id-restart GL_LINES_ADJACENCY other - glsl-1.50-geometry-primitive-id-restart GL_LINE_LOOP ffs - glsl-1.50-geometry-primitive-id-restart GL_LINE_LOOP other - glsl-1.50-geometry-primitive-id-restart GL_LINE_STRIP other - glsl-1.50-geometry-primitive-id-restart GL_LINE_STRIP_ADJACENCY other - glsl-1.50-geometry-primitive-id-restart GL_TRIANGLES other - glsl-1.50-geometry-primitive-id-restart GL_TRIANGLES_ADJACENCY other - glsl-1.50-geometry-primitive-id-restart GL_TRIANGLE_FAN ffs - glsl-1.50-geometry-primitive-id-restart GL_TRIANGLE_FAN other - glsl-1.50-geometry-primitive-id-restart GL_TRIANGLE_STRIP other - glsl-1.50-geometry-primitive-id-restart GL_TRIANGLE_STRIP_ADJACENCY other (These failures were previously hidden due to a flaw in the test: it doesn't check for GL errors. I'll fix the test shortly). Reviewed-by: Kenneth Graunke <kenneth@whitecape.org>
