Yes. From the ARB_texture_rectangle specs:


Additions to the OpenGL Shading Language specification

Add the following keywords:


Add to section 8.7 "Texture Lookup Functions"

vec4 textureRect(samplerRect sampler, float coord)
vec4 textureRectProj(samplerRect sampler, float coord)

No "bias" parameter is allowed because mipmaps are not allowed for
texture rectangles.
