In terms of OpenGL, I’m looking to change the GL_TEXTURE_WRAP_S and
GL_TEXTURE_WRAP_T parameters to GL_REPEAT, but I’m not actually using
OpenGL code, only SDL_RenderCopy with appropriate sized SDL_Rects.
Currently I have a 1x2 surface containing scanline data, and want to scale
it by repeating, not clamping. The benefit being that I can cover an
entire window with a 1x2 texture instead of creating it to be the full
size of the window.
Any advice is appreciated,
Steve A.
