/* 
 Layer which reads text,x,y from SQLite database and shows labels in given coordinates. x and y must be in layer projection,
 which means EPSG:3857 (spherical mercator), or you can use projection.fromWgs() of to convert it.
 
 Note that with layer definition you give database file name and SQL which must return x, y and text - in this order, 
 also filter arguments must be in same number and order (xmin,xmax,ymin,ymax). Do not use this for big datasets, as this query
 is not indexed properly and will become slow with thousands of rows. Use Spatialite for big datasets, as it can do spatial indexes
 and fast reading from tables with millions of items (e.g. global geonames.org database dump).
 
 Usage sample reading from a table "NamesTable" with columns mappos_x,mappos_y,name :
