[cairo] [PATCH 3/6] [gl] Clear the is_clear flag on the temporary glyph mask we create.

[Eric Anholt]

From: T. Zachary Laine <whatwasthataddress at gmail.com>

Normally is_clear is cleared by the caller of one of the 5 basic
entrypoints, but in this temporary surface usage nobody else can do it
for us.

Fixes ft-show-glyphs-table, user-font-rescale, and select-font-face.
