function SetPixel (x : int, y : int, color : Color) : void
Description
Sets pixel color at coordinates (x,y).
Call Apply to actually upload the changed pixels to the graphics card.
Uploading is an expensive operation, so you'll want to change as many pixels
as possible between Apply calls.
If you're constantly regenerating a texture at runtime, it may be faster
to generate an array of pixel colors and set all of them at once with SetPixels.
This function works only on ARGB32, RGB24 and Alpha8 texture formats.
For other formats SetPixel is ignored.
The texture also has to have Is Readable flag set in the import settings.
