Set an additional color value multiplied into render copy operations.
When this texture is rendered, during the copy operation each source color channel is modulated by the appropriate color value according to the following formula:
srcC = srcC * (color / 255)
Color modulation is not always supported by the renderer; it will return false if color modulation is not supported.
