[Bug]: OCIO failed to compile GL program with 1d luts with 2048 length in RV 2024.1.0

What happened?

RV is failing to compile the GL program when OCIO is using 1D luts with length 2048 both in forwards and inverse directions. The error is:

ERROR: Multiple declarations of 'ocio_lut1d_0Sampler' have different types (sampler1D and sampler2D)

I think the 2048 length must be on the limit where OCIO decides to use a 1D GL texture for one direction and 2D for the other, causing a name clash with different types.

List all the operating systems versions where this is happening

macOS 14.3

On what computer hardware is this happening?

Apple macbook pro M1 16GB
