Guile-SDL 0.3.2 available

[Thien-Thi Nguyen]

release notes:

  this release is motivated primarily by the bugfixes, although the
  upgrade was a nice enough experience (interface continuity -- thanks
  Andreas Schiffler!) to be recommendable to anyone...

README excerpt:

  This directory contains Guile-SDL, a set of modules that provide
  bindings for SDL (Simple DirectMedia Layer) to enable Guile
  programmers to do all the nice things you can do with SDL.
  
  Most of the SDL functions have been wrapped with the exception of a
  few functions that were too C-centric.  The SDL Threads and the Audio
  functions haven't been included because of the problems with Guile
  code being run from more than one thread.  However audio programming
  can be done with the module `(sdl mixer)' that requires the SDL_mixer
  library.
  
  Also included is SDL_gfx 2.0.13 (by Andreas Schiffler) and bindings
  for it.

NEWS excerpt:

  - 0.3.2 | 2005-01-23
  
    - bugfix: (sdl sdl) proc `fill-rect' handles alpha/red values > 127
  
        The color used to be extracted as signed instead of unsigned.
        This caused incorrect out-of-range errors for color values whose
        high bit (alpha for ABGR, red for RGBA) was set.
  
    - bugfix: (sdl misc-utils) proc `copy-surface' handles SDL_SRCALPHA
  
        The proc now takes care to clear this flag (and restore it
        afterwards) in the source surface around the blit, so that RGB
        values are copied correctly.  Unfortunately, the actual alpha
        value is lost due to being unconditionally restored as 255.
  
    - procs moved to (sdl gfx): zoom-surface and roto-zoom-surface
  
        Side effect of the upgrade described in the next entry.
  
    - embedded library upgraded: libSDL_gfx 2.0.13
  
        This library (by Andreas Schiffler) is the successor to
        libSDL_gfxPrimitives and libSDL_rotozoom, incorporating their
        functionality and interfaces, and providing other goodies as
        well.  The result for Guile-SDL users is that module (sdl gfx)
        has been augmented w/ the following new procs:
  
        zoom-surface            ;; moved from (sdl sdl)
        roto-zoom-surface       ;; likewise
        draw-hline              ;; rest are completely new
        draw-vline
        draw-aa-circle
        draw-aa-ellipse
        draw-pie-slice
        draw-trigon
        draw-aa-trigon
        draw-aa-polygon
        draw-bezier
        make-fps-manager
        fps-manager-set!
        fps-manager-get
        fps-manager-delay!

        Primitives, Rotation / Zooming, and Managing Frame Rate.
