* it so that applications can enable sRGB write when they want to.
*
* This is not to be confused with GLX_FRAMEBUFFER_SRGB_CAPABLE_ARB. When
* the attribute is GLX_TRUE, it tells the st manager to pick a color
* format such that util_format_srgb(visual->color_format) can be supported
* by the pipe driver. We still need to advertise the capability here.
*
* For GLES, however, sRGB framebuffer write is controlled only by the
* capability of the framebuffer. There is GL_EXT_sRGB_write_control to
* give applications the control back, but sRGB write is still enabled by
* default. To avoid unexpected results, we should not advertise the
* capability. This could change when we add support for
* EGL_KHR_gl_colorspace.
