Font glyph sub-pixel positioning mode. Subpixel positioning provides shaper text and better kerning for smaller font sizes, at the cost of memory usage and font rasterization speed. Use [constant TextServer.SUBPIXEL_POSITIONING_AUTO] to automatically enable it based on the font size.

2D transform, applied to the font outlines, can be used for slanting, flipping and rotating glyphs.
For example, to simulate italic typeface by slanting, apply the following transform [code]Transform2D(1.0, slant, 0.0, 1.0, 0.0, 0.0)[/code].
