From 954974950726f3b6dbc8c5341722c942eade07f1 Mon Sep 17 00:00:00 2001 From: Simon Ser Date: Mon, 10 Oct 2022 09:25:33 +0200 Subject: render/gles2: assert that GL_OES_EGL_image_external is supported The target is set to GL_TEXTURE_EXTERNAL_OES when EGL_EXT_image_dma_buf_import_modifiers [1] returns an external_only flag. That spec states: > In order to support imports for the GL_TEXTURE_EXTERNAL_OES target, a > compatible OpenGL ES implementation supporting GL_OES_EGL_image_external > must be present. Fail hearder when a driver doesn't follow the spec instead of skipping rendering. See [2].
