9bef2bd626 GRIM,EMI: SHADERS: Compute umbra angles cosine on set load instead of for each frame 
Only benefits shaders renderer, as opengl/tinygl renderers leave such
details to the gl library.
Maintain saved-state compatibility by computing on restore.

8d5406720c ENGINES: Add a new 'renderer' option to replace 'soft_renderer' 
'soft_renderer' was a bool and was not useful to select a renderer
in a list with more than two values.

b186c21f85 EMI: Fix wrap around of Layers/Frames 
This patch makes sure, that Layer::_frame is smaller than numLayers
of the bitmap in order to prevent out-of-bounds access to
BitmapData::_layers.

d7e7ee214d GRAPHICS: Enable drawing of bitmaps/tiles with just one sub-image 
Instead of using the number of sub-images to decide whether bitmaps
should be drawn using TIL information, better use the existance
of texture coordinates which are distinctive for tiles.

1fd56d769c GRIM,EMI: SHADERS: Move 3 multiplication per light from CPU to GPU. 
GPU already has to multiply intensity, this change just changes initial
shader-level intensity from fixed 1.0 to data value (after per-game
scaling). Use color w coordinate, as it already used as a boolean light
switch.

a8460f4f3f EMI: Check bit in mesh face flags to disable lighting 
Use bit 0x20 in the mesh face flags to disable ligthing. This
fixes the problem that once a previous screen is used as
texture (e.g. in the intro or for the transition effects
in set kab when walking eastwards or westwards), it is shown
too dark due to the applied static lighting for overworld
actors.

28804cd9fe EMI: Flip y coordinate when creating screenshot textures 
With OpenGL the created textures were mirrored in y direction
because OpenGL uses a different coordinate system where (0, 0)
is the bottom left corner.

6d226501b5 EMI: Implement mesh-specific alpha values 
- if Lua_V2::SetActorGlobalAlpha() is called with a mesh name,
  set a mesh-specific alpha value / mode
- use this alpha value in drawEMIModelFace()
- fixes the problem that the whole actor vanishes in some scenes
  (e.g. when entering or leaving the porch of the of LUA bar)

598bfc5fe9 GRIM/EMI: Call glViewport for apitrace compatibility 
glViewport needs to be called once to avoid the apitrace
error: "could not infer drawable size (glViewport never called)".

This fixes the problem that all apitrace framebuffer pictures
had a default size of 32x32 instead of the correct resolution used
in residualvm.

c2318c7153 EMI: Use half-transparent plane to implement dimScreen (OpenGLS) 
- instead of re-calculating the color values when dimming the screen,
  better draw a half-transparent plane after drawing all non-overworld
  characters
- fixes the issue that overworld actors were dimmed and that the
  pause screen is transparent when the inventory is open

cbbf60d155 EMI: Check another bit in the mesh face flags to enable blending. 
Bit 0x40000 in the mesh face flags (set only in the intro) should
enable blending, too. This fix lets the various screens of the intro
fade into each other.
