+ *
+ * Desktop GL is fairly reasonable in its handling of sRGB: You can ask if
+ * your renderbuffer can do sRGB encode, and you can flip a switch that does
+ * sRGB encode if the renderbuffer can handle it. You can ask specifically
+ * for a visual where you're guaranteed to be capable, but it turns out that
+ * everyone just makes all their ARGB8888 visuals capable and doesn't offer
+ * incapable ones, becuase there's no difference between the two in resources
+ * used. Applications thus get built that accidentally rely on the default
+ * visual choice being sRGB, so we make ours sRGB capable. Everything sounds
+ * great...
+ *
+ * But for GLES2/3, they decided that it was silly to not turn on sRGB encode
+ * for sRGB renderbuffers you made with the GL_EXT_texture_sRGB equivalent.
+ * So they removed the enable knob and made it "if the renderbuffer is sRGB
+ * capable, do sRGB encode". Then, for your window system renderbuffers, you
+ * can ask for sRGB visuals and get sRGB encode, or not ask for sRGB visuals
+ * and get no sRGB encode (assuming that both kinds of visual are available).
+ * Thus our choice to support sRGB by default on our visuals for desktop would
+ * result in broken rendering of GLES apps that aren't expecting sRGB encode.
+ *
+ * Unfortunately, renderbuffer setup happens before a context is created. So
+ * in intel_screen.c we always set up sRGB, and here, if you're a GLES2/3
+ * context (without an sRGB visual, though we don't have sRGB visuals exposed
+ * yet), we go turn that back off before anyone finds out.
