…k buffer to allow better feedback effects/ no functional change for the user except fp32 RGBA in texPreviousFrame (was 8bit before)

(oops, this function was added for a different change. will come with another PR)

argh, I forgot that other backends exist. I don't know shit about DX unfortunately. |

use render-to-texture instead of pixel readback, use 32bit texture as back buffer. no functional change for the user except fp32 RGBA in texPreviousFrame (was 8bit before). to allow better feedback effects (like fading colors more gracefully, and also shenanigans like particle systems stored in pixel colors)
