From 4225b3220ef4bf50f0d9403f812ea94d50c4ee59 Mon Sep 17 00:00:00 2001 From: Herb Derby Date: Wed, 9 May 2018 16:36:11 -0400 Subject: [PATCH] Have draw(Text|PosText|PosTextH) use a single entry on the device Handle the positioning of drawText at the canvas layer. Simplify the code by removing similar implementations.
