Possibility to create 1D textures

[tcdude]

Is your feature request related to a problem? Please describe. It would be nice to create 1D textures that can be used in glsl shaders using sampler1D

Describe the solution you'd like Adding new init function(s) to graphics4+5/texture.h to initialize 1D textures.

Describe alternatives you've considered I can work around it by using a 2D texture with a height of 1 and do lookups in the shader using the respective declarations and calls.
