`r_screenshotJpegQuality`

OpenJK

Needs review. The inventory/provenance evidence is recorded, but some behavior, options, or attribution still lacks a direct user-facing source.

Controls r_screenshotJpegQuality in the renderer module. Consult the cited behavior reads before relying on values not listed here.

Provenance

Origin: OpenJK

Ultimate-origin introduction: 714c868b42c6 in OpenJK (content authored 2013-04-16, integrated 2013-04-16)
Upstream registration evidence: code/rd-vanilla/tr_init.cpp:1682
Attribution method: squash-feature-group-explicit-credit
Attribution confidence: medium
Notes: The identifier’s single-prefix squash feature group explicitly credits openjk. Dated commit evidence identifies later registration changes relative to the origin snapshot.

Dated project introductions

Authored dates come from the exact registration’s first content commit, PR dates identify when work was proposed to each project, and integration dates come from each first-parent mainline. A project merging first does not override earlier upstream authorship or submission.

Later changes

These commits occur after the ultimate-origin introduction on TaystJK’s inherited first-parent lineage. Registration evidence is exact; behavior evidence requires a changed bound cvar reference or a changed registered command-handler hunk.
