VDP opengl plugin version 1.1

This plugin implements the VDP1 and VDP2 processors. The VDP1 emulation is quite fast but misses some VDP1 features such as mesh transparency which is replaced by alpha blending.
VDP2 emulation is not very fast and lacks a LOT of VDP2 features. Rotation backgrounds are not emulated.

You can modify the rendering resolution through the menu. You can also activacte or desactivate bilinear filtering.
To speed up rendering VDP2 planes can be disabled separately.

Planes and sprites priority emulation has been enhanced but is still incorrect in some games (radiant silvergun..)

in order to switch to fullscreen mode you can use the menu or press ALT+ENTER
