f5ca94b1ef Remove frame buffer validity check by buffer address written at the origin 
of the buffer in RDRAM. This is unreliable method.

cbdacb58d8 Don't call FrameBufferList::_findBuffer until buffer's actual height is not detected. 
Otherwise wrong buffers can be removed.

f4e1afa30c Split hack_noDepthFrameBuffers on two options: 
hack_noDepthFrameBuffers and hack_blurPauseScreen.

hack_blurPauseScreen is for games, which copy color buffer into depth buffer area,
blur it and use as background image. Examples: Conker BFD, Mickey USA

hack_noDepthFrameBuffers is for games, which never use depth buffer area as texture
Example: F-1 Pole Position, Mario Golf.

e9b406d134 Add special frame buffer flag for Ogre Battle backgrounds.

b0e86e2cbc Limit frame buffer height by VI.height if buffer width == VI.width 
Fixed flicker in Bomberman 2 map screen. The game sets scissor.lry = 250 here,
while VI.height is 240. Actual frame buffer height is 240. Making it 250
causes wrong selection of that buffer on VI update.

33806e7170 Fix depth calculation. 
Problem:
N64 formula for screen z is screenZ = z/w*viewport.vscale[2]+viewport.vtrans[2]
OpenGL uses z/w, vscale and vtrans are set in glViewport and they always equal.
viewport.vscale[2] can be not equal to viewport.vtrans[2] and in that case
standard OpenGL z compare does not work correct.

Solution:
use N64 formula for screenZ in fragment shader.

Fixed Twine: wrong depth for the arm #115

into wrong buffer.

bc34838db6 Fix pause screen in Conker BFD. 
How it work:
- content of previous main frame buffer is copied into depth buffer area.
- CPU applies blur to th eimage in depth buffer area.
- Depth buffer is used as background texture for pause screen.

Solution:
1. Do not use depth buffer FBO as texture. Image must be load from RDRAM.
2. If current color image is depth image and previous color buffer is used as
texture for it, copy content of color image in RDRAM to depth image area.
