/**
* Number of floating point numbers that represent a single glyph in the SDF vertex buffer.
*
* @remarks
* The vertex buffer contains:
* - 6 vertex positions
* - 6 texture coordinates
* - = 12 positions/coordinates per glyph
*
* Each vertex position and texture coordinate consist of 2 floating point numbers (x/y).
* So there are 12 * 2 = 24 floating point numbers that make up a single glyph.
