The calendar report is ignoring rule.precedence.color and rule.color.merge settings

[d2718nis]

Current behavior

The calendar report does not respect the rule.precedence.color or rule.color.merge settings as expected. At the same time, both the taskrc (precedence, merge) and task-color (precedence, merge) man pages lack any mention that they do not apply to the calendar report.

Example

In the following example, I set rule.precedence.color=scheduled,due intending that dates with both scheduled and due tasks (e.g., November 22nd) would adopt the color defined for scheduled tasks. However, the color for that date defaults to the due task color instead of prioritizing scheduled.

Additionally, I set rule.color.merge=0 to prevent blending of scheduled and due colors, but the colors are still merged.

Analysis

A quick review of the source code for the calendar report reveals:

1. Precedence handling appears to be hardcoded, as seen here, and depends on the order of if clauses
2. The blend() method from libshared is used in several places, disregarding the rule.color.merge setting
