[freetype2-demos] master 4449ff5: [graph] Avoid unnecessary memory zeroing.

[Werner Lemberg]

branch: master
commit 4449ff5a8d18eec1bdb93009cd8bf499558342cb
Author: Alexei Podtelezhnikov <apodtele@gmail.com>
Commit: Alexei Podtelezhnikov <apodtele@gmail.com>

    [graph] Avoid unnecessary memory zeroing.
    
    * graph/x11/grx11.c (gr_x11_surface_init): Call `malloc` explicitly.
    * graph/grblit.c (grGetSaturation, grGetConversion): Call `malloc`
    and `memset` explicitly even though this code is unused.
