Rename TouchEnsureSprite to TouchBuildSprite and event type checks

Browse Source 
The function will be used for building a sprite for pointer emulation
after an explicit device grab. This commit refactors the code so that
TouchBuildSprite will function with any event type and moves the checks
to the caller.
