Description

We can probably just query the depth bits in the bound framebuffer, or similar.

See https://github.com/servo/webrender/issues/3186 for context.

Contributor guide

Research direction
Investigate how to query the number of depth bits in the bound framebuffer (e.g., using glGetFramebufferAttachmentParameteriv) and ensure this check runs during the first render or initialization.
