Committed: Sat Dec 29 14:23:35 2012 UTC (11 years, 4 months ago) by sf-exg
Content type: text/plain

Changes since 1.383: +2 -2 lines
Log Message:
Revise preprocessor macros that control the core bg image code.

Move definition of BG_IMAGE_FROM_FILE in rxvt.h and add analogous
BG_IMAGE_FROM_ROOT macro that is set if the code to manage the root
pixmap is needed.
