Subject: The GLSL texture function returns a float for shadow samplers
X-Git-Url: http://git.tdb.fi/?a=commitdiff_plain;h=cb91a6133e1671a4d51a39429ccb35726da9be0d;hp=cb91a6133e1671a4d51a39429ccb35726da9be0d;p=libs%2Fgl.git

The GLSL texture function returns a float for shadow samplers

In contrast with the legacy shadow2D function, which returned vec4.
