[libcamera-devel] [PATCH v2 1/2] qcam: assets: shader: bayer_8.frag: Add precision

[Kunal Agarwal]

Currently there is no defined precision for data types
which results in compilation errors for shader.

Adding precision mediump for sufficient and required
range and accuracy. Also suitable for textures.
Precision highp also works but is not supported by some
older hardware devices and consumes more memory.
