The Mesh module provides a set of predefined point marker shapes

Each standard point marker has two attributes: type (defines shape
form) and scale factor (defines shape size).
It is also possible to load a point marker shape from an external file.
This file should provide a description of the point texture as a set
-of lines; each line is represented as sequence of "0" and "1" symbols,

where "1" symbol means an opaque pixel and "0" symbol means a

of the longest line in the file, expanded to the nearest byte-aligned
value. The height of the texture is equal to the number of non-empty
lines in the file. Note that missing symbols are replaced by "0".
