// Shifting layer
/*
Input:
1) Three arguments, first is Layer, second and third are double. Interprets as new absolute position in cm.
2) Pairs list. Names are l (layer), x, y, relx (rx), rely (ry). Pair with name l may be absent, in this case search in list and using as layer object with ObjectGMTLayer type. x and y are absolute positions in cm, relx and rely are shift from current position. x (y) and relx (rely) are mutually exlusive, but x (y) and rely (relx) can be used simultaneously. If position for some axis is absent, then this position is unchanged.

// Draw frame with tics
/*
Input: pairs list.
proj or projection or unnamed GMTProjection parameter - projection. This is mandatory argument.
xtics - position of tics for x axis. Can be none, up, down or both. Default is down.
ytics - position of tics for y axis. Can be none, left, right or both. Default is left.
xint - tics interval for x axis. Numerical value or word auto. Default is auto.
yint - tics interval for y axis. Numerical value or word auto. Default is auto.
domain - coordinates domain. Can be pos (0:360), neg (-360:0) or center (-180:180) (only for geographic projections). Default is pos.
mark - using letters (W, E, S, N) instead of sign for coordinates (only for geographic projections). Can be yes or no. Default is no.
font - font using for annotations. Default is 12,Times-Roman,black.
offset - distance from end of tick-mark to start of annotation in cm. Default is 0.18.
framewidth - width of frame (only for geographic projections) in cm. Default is 0.1.
framepen - pen for drawing frame. Default is 0.35,black.
ticklen - lenght of tick-marks in cm. Default is 0.18.
tickpen - pen for drawing ticks. Default is 0.3,black.
trans or transparency - transparency level, double from 0 to 100. Default is 0 (opaque).
model - transparency model, string. Choose from Color, ColorBurn, ColorDodge, Darken, Difference, Exclusion, HardLight, Hue, Lighten, Luminosity, Multiply, Normal, Overlay, Saturation, SoftLight, and Screen. Default is Normal.
rx or relx - shift layer on x cm in horisontal direction. Default is 0.
ry or rely - shift layer on y cm in vertical direction. Default is 0.
