Minimum OpenGL version?
The recent commit 81cace02 appears to have changed our minimum version of OpenGL to something older than 4.5, which is swell. We should probably document what it is.
But also, we're reporting minimum required OpenGL versions to the application in XrGraphicsRequirementsOpenGLKHR, populated by xrGetOpenGLGraphicsRequirementsKHR - this is what the application must support to use Monado. It currently reports 4.5. It should at least be modified to whatever the new, lower minimum is now. However:
- Is an application required to use that high of a version? or is it just that we use that high of a version internally?
- Does this mean I can't write OpenGL+OpenXR apps using OpenGL 1.1 and run them on Monado? (I suppose I wouldn't be too surprised.)
- How about OpenGL 2.0? (again not super surprised, but...)
- 3.0 compatibility profile? (Think this works with OSVR so I'd be surprised if it didn't work here.)
