LibGfx: Remove somewhat outdated comment

Browse source 
Most of these optimizations have been tried now, so this comment is a
bit misleading.

// This a pretty naive implementation of edge-flag scanline AA. // This an implementation of edge-flag scanline AA, as described in:
// The paper lists many possible optimizations, maybe implement one? (FIXME!)
// https://mlab.taik.fi/~kkallio/antialiasing/EdgeFlagAA.pdf // https://mlab.taik.fi/~kkallio/antialiasing/EdgeFlagAA.pdf
// This currently implements:
// - The scanline buffer optimization (only allocate one scanline)
// Possible other optimizations according to the paper:
// - Using fixed point numbers
// - Edge tracking
// - Mask tracking
// - Loop unrolling (compilers might handle this better now, the paper is from 2007)
// Optimizations I think we could add:
// - Using fast_u32_fills() for runs of solid colors
// - Clipping the plotted edges earlier
