Modified Files:
edje_calc.c edje_data.c edje_private.h
Log Message:
add linear gradient specific fill options
used (inside a part description) as follows:
Horizontal from left to right filling entire part:
gradient {
spectrum: "black_to_white";
rel1 {
relative: 0 0.5;
offset: 0 0;
}
rel2 {
relative: 1 0.5;
offset: -1 0;
}
}
Diagonal from top left to bottom right:
gradient {
spectrum: "black_to_white";
rel1 {
relative: 0 0;
offset: 0 0;
}
rel2 {
relative: 1 1;
offset: -1 -1;
}
}
If either rel1 or rel2 is present in the gradient block of a linear gradient,
these will override any angle/origin/size specified in the fill block ('spread'
is still honored).
