Added layers to enable mapmarks to be prioritized
Backwards compatible
negative: text on clear background looks bad (maybe more advanced alpha channel will fix that?)

Or it could be done just by sorting TMapMarkList.FList by TMapMark.Layer (probably easier, faster and eliminates downside)

Interesting! Thanks for your input! I think I start with adding layerIDs and sorting the list by this field, leaving layer bitmaps to the future.

Done partially in v0.6.0, just layer numbers for now. I made them Byte to benefit from sets
