Grx.put_scanline
Writes @scan_data to the current context using the op operation.
Data values in @scan_data must fit #GRX_COLOR_VALUE_MASK otherwise the results are implementation dependent. So you can't supply operation code with the pixel data!
- x1
the starting X coordinate
- x2
the ending X coordinate
- y
the Y coordinate
- scan_line
the data to write
- op
the color operation
