Avoid implying that normalized texture cannot be signed #257

Closed gnl21 closed 2 months ago

gnl21 commented 2 months ago

GL does support signed normalized textures, so change the format list in the GLSL spec to remove the word "unsigned" that implied the signed variants were not valid.

Fixes internal issue 76. Thanks, @lexaknyazev
