// Using formats that match cairo's formats.

/*
For internal cairo we have the option --enable-cairo-rgba which is potentially
useful for Android or Online to switch the rgb components. For Android cairo then
matches the OpenGL GL_RGBA format so we can use it there where we don't have
GL_BGRA support. Similarly for Online we can then use cairo's pixel data
without needing to swizzle it for use as a canvas ImageData.
