| x | X coordinate of the pixel to set. |
| y | Y coordinate of the pixel to set. |
| mipLevel | Mip level to sample, must be in the range [0, mipCount[. |
Color Pixel color sampled.
Returns pixel color at coordinates (x, y).
If the pixel coordinates are out of bounds (larger than width/height or smaller than 0),
they will be clamped or repeated based on the texture's wrap mode.
Texture coordinates start at lower left corner.
If you are reading a large block of pixels from the texture, it may be faster
to use GetPixels32 or GetPixels which returns a whole block of pixel colors.
Texture.isReadable must be true. GetPixel is not available on Textures using Crunch texture compression.
