webP and webM support in LiveCode

[Alejandro Tejada]

I forgot a very important aspect of implementing webP in LiveCode engine.

For a first implementation, LiveCode could import (decode) only static -not
animated- webP images and exclude the option of exporting images as webP
(excluding the encoder from the engine). This would reduce the complexity
of this task.

Now, I have to check if these optimized JPG and PNG encoders produce better
results with my own test images:

Anyone interested in the topic of image optimization could learn a lot from
this webpage too:

Have a nice weekend!
