From 85ba2610cf05a75b52681f381bba2da3ba37b984 Mon Sep 17 00:00:00 2001 From: Lei Zhang Date: Tue, 10 Apr 2018 17:55:46 +0000 Subject: Change FillRectWithBlend methods to take FX_RECT by const-ref. They currently take const FX_RECT*, but the pointer is never nullptr. Also add a comment to explain why FX_RECT is the way it is. It has the same layout as a win32 RECT.
