Subject: [image] Scale images not using data beyond the edge of the last pixel
X-Git-Tag: 0.7.1~11
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=a4836e83fe3baa74ab3a6321978d36ef95a394f8;p=thirdparty%2Fplymouth.git

[image] Scale images not using data beyond the edge of the last pixel

When using 1 pixel wide images and stretching them, the result is a fade
between the pixel data and the transparent pixels beyond the end of the image.
