Confirmed for Mesa 18.3.6. R100-class GPU too (ATI Mobility Radeon 7000 IGP).
R100 class Radeon GPUs only support OpenGL up to 1.3, while GLSL has only become a thing as an extension for 1.4 and finally an integral feature in 2.0. Does that mean OpenGL Shading Language support is nowadays necessary for Mesa?
