Bug #262
Light + Halo not centered to sprite correctly
Description
Run jDoom with the Batman TC available here:
http://www.doomworld.com/idgames/index.php?id=12391
Towards the end of MAP01 is a room with a balcony
staircase and wall lights. These wall lights are
sprites (CANDA0 in batman.wad) Doomsday correctly
generates a dynlight+halo for this sprite but the
center for which that is calculated in
GL_CalcLuminance() is incorrect.
This results in a light source that is clearly in the
wrong place and a halo that is floating in mid air,
this looks quite bad :-(
CANDA0 in batman.wad is 19x128 and consists of at least
75% alpha'd pixels.

Fixed for 1.9.0.
Improved algorithm to clip 100% alpha regions from the src
buffer before calculating luminance in GL_CalcLuminance().
