Bug 225423 – [GLIB] fast/canvas/canvas-composite-text-alpha.html is failing since r277024

• Component: New Bugs
• Status: NEW

[Diego Pino]

r277024 added preliminary support for specifying a color space for 2D canvas. Since then these two tests are failing:

  fast/canvas/canvas-composite-text-alpha.html [ Failure ]
  fast/canvas/canvas-color-space-display-p3.html [ ImageOnlyFailure ]

'canvas-color-space-display-p3.html' is a new tests added in r277024.
