        here's the wild thing: 128*128 is pico8's resolution, and an integer is 4 bytes. 128*128*4=65536 bytes, which is the *exact* maximum size of a uniform block on my nvidia card. down to the byte. whew.

          really, 4 bytes is way too big for an index, but i dont know how to pass an integer type smaller than that. 8 or even 4 bits is plenty for what i intend to do. any ideas on how to pass arrays of smaller integer types as uniform blocks to opengl?

        basic idea is: there's a buffer of 128*128 integers that acts as the framebuffer. there's an array on the CPU side that you write into to draw. that array then gets sent to the GPU with a palette and each pixel looks up its index in the framebuffer and its color from the palette

          far from perfect, but here's some circles

            better circles. renderer now guarantees square pixels, working on centering
