1263678 - Don't blacklist OGL on Linux if we don't have TextureFromPixmap

Status: RESOLVED FIXED

(Core :: Graphics: Layers, defect)

Description

[Benoit Girard (:BenWa)]

This blacklist doesn't make any sense since we don't use the extension.

Attachment: don't block OpenGL layers when lacking EXT_texture_from_pixmap

We don't actually use TFP unless it is pref'd on at current, and when it is pref'd on, it is broken anyway until we have time to reevaluate it and GL context initialization for it.

Since OpenGL layers still offers a performance advantage over basic layers even without TFP, it makes no sense to blacklist because of a lack of TFP at present.

Any reason to keep the code?
Are you planning to resurrect a variant at some stage?

Release Note Request (optional, but appreciated)
[Why is this notable]:
[Suggested wording]: Linux installations not supporting EXT_texture_from_pixmap OpenGL extension are not blocked from OpenGL acceleration anymore.

Relnote -, pretty technical description that we are not sure would be helpful to end users.
