Hi, this is currently used by 4 packages but there are many more to come, especially in the dev-qt/* and kde-*/* categories where 'gles2' is being renamed to 'gles2-only' where appropriate. Its purpose and description is really the same everywhere.
Description: "Use GLES 2.0 or later instead of full OpenGL" See also: - USE={egl,gles{,1,2,3}} flags are a total mess [1] - [gentoo-dev] Addressing split usage of USE=gles[123] [2] - PRs in prepration for gentoo.git [3], kde.git [4] and qt.git [5] I plan to introduce this real soon, coinciding the necessary revbumps with upcoming/in-preparation Qt 5.14.2 and KDE Plasma 5.18.4 version bumps.
