aText	is the text to be drawn.
aPosition	is text position.
aSize	is the cap-height and em-width of the text.

Returns

new cursor position

Draws a single line of text.

Multiline texts should be split before using the function.

Parameters

aGal	is a pointer to the graphics abstraction layer, or nullptr (nothing is drawn)
aBBox	is an optional pointer to be filled with the bounding box.
aText	is the text to be drawn.
aPosition	is text position.
aSize	is the cap-height and em-width of the text
aAngle	is text angle.
aMirror	is true if text should be drawn mirrored, false otherwise.
aOrigin	is the point around which the text should be rotated, mirrored, etc.

Returns

new cursor position in non-rotated, non-mirrored coordinates
