      Have movefile() leave the original file with the delete attribute · 4c912de9
      Rob Swindell authored
      This has the effect of the file being listed as absent/deleted in the listing that's in memory. As requested by Phil, plt via irc.
      
      Moving a file after this change did result in a crash once, but I couldn't reproduce it with a debugger attached.

      Fix bug in last commit · a40cda0c

      Pixes set via setpixels() were only set in the "blink off" screen
      and not in the "blink on" screen... so they all reverse blinked.

      1) Keep a rectangle updated per-screen rather than regenerate each time
      2) Strip palette info when putting pixels into rectangles rather than
         during scaling
      3) Tighten up the screen locks a bit
      4) Don't require a full resend of both screens on an update request
      5) Only force a redraw for cursor movement when the cursor is visible
         (And force it whenever the cursor changes)
      6) Avoid doubles in interpolation
      7) Heavily optimize interpolate_height()
         interpolate_width() likely doesn't need it because it's generally not
         used and also it reads from the next pixel in memory making the
         prefetchers job easier.
      8) Fix some memory-leak-on-error issues
      9) For ARGB8 XImages, manipulate the data directly rather than through
         XPutPixel()
      
      At this point, the scaling and X11 output time is heavily dominated by
      cache misses.  The only really effective way to reduce this hit is to
      spread the work across all the L3 caches in the system or move it into
      the GPU.
      
      With the latest updates, at the SyncTERM menu, over 90% of the time is
      spent in the rendering pipeline, and over 90% of that time is spent
      thrashing the caches... the only real easy win left is vectorizing, but
      that's highly compiler specific.
      
      To that end, I've switched to -O3 for release builds.  There was a comment
      that -finline-functions broke Baja "badly", but that's clearly false since
      -f-inline-functions has been part of -O2 for quite a while now, and Baja
      doesn't seem any more broken that it ever was.
