This patch introduces new functions to quickly grab a pointer to a
vector type. For example:
glsl_type::bvec(4) returns glsl_type::bvec4_type
glsl_type::ivec(3) returns glsl_type::ivec3_type
glsl_type::uvec(2) returns glsl_type::uvec2_type
glsl_type::vec(1) returns glsl_type::float_type
This is less wordy than glsl_type::get_instance(GLSL_TYPE_BOOL, 4, 1),
which can help avoid extra word wrapping.
