I there a programmatical way (e.g. OpenGL command) to determine the maximal line width IN PIXELS supported by my GPU.
I recently worked with a OpenGL buffer with width ~ 50000 pixels and got bad results.
Decomposing the image with smaller line widths solved the problem.
However to robustly implement this solution I would need to know what the maximal width the particular GPU supports.

I was expecting a OpenGL command that returns exactly that.
