6d3637849b Added a fast xor_line() function. Uses XDrawLine with GXxor mode. 
Only used for front-buffer window/pixmap rendering, GL_FLAT shade model,
no Z test or other fragment operations.

0efc17c105 Add Wrapper field to gl_renderbuffer. Used for wrapping one renderbuffer 
with another, such as wrapping a hardware/win-sys RGB renderbuffer with a
software-based alpha buffer.
Previous alpha buffer wrapping was conflicting with the X driver's
xmesa_renderbuffer structure containment/inheritance.  That lead to
memory corruption.

7b01068a23 Enable GL_ARB_texture_mirrored_repeat on Savage4. Refactor the code that 
sets the texture wrap mode and texture filter mode for Savage4 to the new
functions savage4_set_wrap_mode and savage4_set_filter_mode.

This was tested with texwrap and tunnel.

da9f65268d New set_fetch_functions() to set a gl_texture_image's FetchTexel functions 
from the gl_texture_format's functions.
Added "adaptor" functions to allow sampling a float-valued texture with
GLchans and vice versa.  This will allow trimming down the number of
texture fetch routines.
