vrend, tex: Support fake multisample correctly
A texture is non-multisample when the nr_samples == 0, for the value 1 fake multisampling is assumed and a GL_TEXTURE_2D_MULTISAMPLE should be created.
Closes: #44 (closed)
Fixes dEQP tests that pass on the host when run with softpipe: dEQP-GLES31.functional.shaders.builtin_functions.texture_size. samples_1_texture_2d samples_1_texture_2d_array Pass -> Fail samples_1_texture_int_2d Pass -> Fail samples_1_texture_int_2d_array Pass -> Fail samples_1_texture_uint_2d Pass -> Fail samples_1_texture_uint_2d_array Pass -> Fail dEQP-GLES31.functional.texture.multisample.samples_1. sample_position use_texture_color_2d use_texture_color_2d_array use_texture_depth_2d use_texture_depth_2d_array use_texture_int_2d use_texture_int_2d_array use_texture_uint_2d use_texture_uint_2d_array
