Fix the progress animation to get displayed at the original size and not squished.

The progress animation was showing up squished vertically to about 10 pixels on linux, and to
fix that we now create bitmaps with the proper colour depth ourselves and draw the animation
frames onto it instead of using the built-in method.

BUG=53598
TEST=manual, test that the speech recognition progress animation shows up as expected and not squished.
