| # ES1 Status |
| |
| ES1 is implemented entirely in the front-end using features from GLES3.0. Therefore, every backend |
| with GLES3 support (i.e. everything other than D3D9) supports GLES1 as well. |
| |
| ANGLE passes GLES1's `MustPass`, however there are known missing features. |

| ### Notes [1] |
| * Logic op is implemented through the `ANGLE_logic_op` or `EXT_framebuffer_fetch` extensions. |
| * Currently, these are supported on the Vulkan and GL backends only. |
