dmenu alpha: cleanup patch, Making Alpha Small Again (MASA)
Removed ".orig", ".rej" and patching leftovers...
Other:
- Change the default value from 0xff to 0xee to have some effect.
- Fix correctly initialize alpha values:
scheme[j] = drw_scm_create(drw, colors[j], 2, alphas[j]);
used to be uninitialized:
scheme[j] = drw_scm_create(drw, colors[j], 2, alphas[i]); (wrong)
- Change order of drw_scm_create() arguments (no difference intended).
- Small code-style changes.
index.md: Sort index from most recent to old (top to bottom).
Provided from the goodness/evilness of my heart.
I do not use this patch or am going to maintain it.
