<p>Changes the value of the pixel (x,y). </p>
<p>Pixel coordinates starts at the left-top corner of the image, and start in (0,0). The meaning of the parameter "color" depends on the implementation: it will usually be a 24bit RGB value (0x00RRGGBB), but it can also be just a 8bit gray level.</p>
<p>You can also use a TColor() type as input and it will be automatically converted to size_t.</p>
<p>This method must support (x,y) values OUT of the actual image size without neither raising exceptions, nor leading to memory access errors. </p>
