From 6430230d1fdab4c056300375606389d2b655f50b Mon Sep 17 00:00:00 2001 From: Simon Ser Date: Tue, 1 Jun 2021 15:55:30 +0200 Subject: render: add wlr_renderer_begin_with_buffer This allows compositors to choose a wlr_buffer to render to. This is a less awkward interface than having to call bind_buffer() before and after begin() and end().
