fortplot_raster_markers

Raster marker drawing functions

This module provides specialized drawing functions for various marker types including circles, squares, diamonds, and X markers. All functions use antialiasing and support separate edge/face colors for complex markers.

All marker functions use the same coordinate system and rounding approach as the primitive drawing functions to ensure perfect alignment with lines.
