// Most LCD monitors use horizontal RGB stripe ordering, where each pixel
// consists of three vertical subpixel columns (red, green, blue) from
// left to right. Backends without exact per-channel compositing may honor any
// requested layout by rendering a portable grayscale glyph mask instead.
//
// Re-exported from text.LCDLayout for convenience so users do not need
// to import the text subpackage for this common setting.
