Shaders, and limitations on plugins access to drawing surface

[Monsieur OUXX]

Hi everyone,

This thread is meant to cover 2 topics :

1) Shaders
I searched, and didn't find any recent thread about shaders. Either color shaders or displacement shaders. I think AGS is now technologically mature enough to allow massive use of sharders (the not-so-cool-anymore bloom, heatwaves, flashes, fake palette cycling, etc.). Did I miss the big fat plugin that already does it?

2) Limitations on plugins access to drawing surface/drawing events
I think I remember reading that plugin developers are not very happy with the access given to the drawing surface, because of some limitations that don't allow them (in some circumstances) to write in the right place at the right time (game-loop wise).
Is it true, or is it a problem from the distant past?
