  Cut MAX_COLOR_ATTACHMENTS_WITH_ACTIVE_PIXEL_LOCAL_STORAGE_ANGLE
  
  Since the number of real devices that support framebuffer fetch, but do
  not support draw_buffers_indexed, is effectively zero,
  MAX_COLOR_ATTACHMENTS_WITH_ACTIVE_PIXEL_LOCAL_STORAGE_ANGLE is an
  unnecessary complication. These hypothetical devices can fall back on
  shader images or just not support pixel local storage at all.
  
  This closes the door for WEBGL_shader_pixel_local_storage to ever be
  implemented on top of the ES2 extension that inspired it all,
  EXT_shader_pixel_local_storage, but WebGL can just use framebuffer fetch
  instead, or maybe even EXT_shader_pixel_local_storage2 some day.
  
  This dramatically simplifies the WEBGL_shader_pixel_local_storage
  extension.
