M1 Mac Error: "UNSUPPORTED (log once): POSSIBLE ISSUE: unit 2 GLD_TEXTURE_INDEX_2D is unloadable and bound to sampler type (Float)"

# Setup

- JDK: 1.8 (Amazon Coretto 1.8)
- **(M1 Max)** Mackbook Pro 16 2021.
- MacOs Monterey 12.0.1

# Issue:

```
UNSUPPORTED (log once): POSSIBLE ISSUE: unit 1 GLD_TEXTURE_INDEX_2D is unloadable and bound to sampler type (Float) - using zero texture because texture unloadable
```

This doesn't actually seem to affect the output of the program. It still runs completely as expected.

This seems to be a common issue that is specific to GLSL and M1?

# Repro steps:

The following will repro the issue.
```
import com.soywiz.korge.Korge
import com.soywiz.korge.view.circle
suspend fun main() = Korge() {
circle {

}
}
```

This however, does **not** reproduce the issue:
```
import com.soywiz.korge.Korge
suspend fun main() = Korge() {
}
```

Start by running the provided M1 reproduction with circle and compare it with the empty Korge example. Trace the rendering and GLSL texture-sampler behavior that produces the warning; done means the warning is resolved without changing the program's output.
