evas: Fix classic text styles with filters in textblock 

Textblock filters support RGBA input which means legacy styles
can be used in conjunction with filtering. Not recommended, but
it works. Note: We may decide to drop this behaviour and use
alpha-only inputs for simplicity.

Still missing: support for filtering strikethrough, underline, or
embedded items
