<div>Subject: [PATCH] gl: bind cairo-gl backend to apple's NSOpenGL and apple's</div>
<div> OpenGL instead of mesa's GLX and GL.  It is not possible to create</div>
<div> cairo_gl_surface to use apple's OpenGL directly.</div>
<div><br>
</div>
<div>Few notes:</div>
<div>1. disabled gl-surface-source test because it uses GLX, need to revise the</div>
<div>test</div>
<div>2. offscreen and NSView-based surface work fine, I have not implemented for</div>
<div>virtual screen yet.</div>
<div>3. After install macport's mesa package, it is possible to use GLX on mac,</div>
<div>but GLX and NSOpenGL are mutually execlusive.</div>
<div>4. To use NSOpenGL "./configure --enable-gl=yes --enable-glx=no</div>
<div>--enable-nsgl=yes</div>
<div>5. To use GLX "./configure --enable-gl-yes --enable-nsgl=no</div>
<div>--enable-glx=yes"</div>
<div>6. make test on NSOpenGL "make test TARGETS=nsgl"</div>
