Subject: [PATCH] Use GL_DRAW_BUFFER0 instead of GL_DRAW_BUFFER for GLES
compatibility
ARB_draw_buffers is part of GL 2.0, so GL_DRAW_BUFFERS0 is always
available, and contrary to GL_DRAW_BUFFER it is also valid for GLES
(part of GLES 3 or as EXT_draw_buffers).
This also matches the universal use of glDrawBuffers instead of
glDrawBuffer.
At least with MESA, GL_DRAW_BUFFER and GL_DRAW_BUFFER0 always return the
same value. GL_DRAW_BUFFERn is also used in several places already.
