#!/bin/sh -e
# TASK
#   Render menu background layers with VERSION string
#
# NOTES
#   It is necessary to have the Xolonium font installed on the system,
#   because svg rendering tools cannot handle embedded or linked fonts.
#   To compensate for filter rendering errors and to reduce rbg noise,
#   the svg files are rendered at a large size and then scaled down.
#
# DEPENDENCIES
#   librsvg
#   imagemagick
#   Xolonium-Regular font
#
# USAGE
#   ./render-version.sh [--no-font-check] DATADIR VERSION
#
# USAGE EXAMPLE
#   ./render-version.sh ~/.xonotic/data "1.0"
