+ 	* src/glitz.c: New internal composite interface. This new interface
+ 	almost completely replaces the old way to do composite. Only some
+ 	parts of the old interface are left as fall-back for cases where
+ 	hardware is not capable of using this new much improved interface.
+ 	New interface is simpler and much more correct then the old one.
+ 	Different fill types and projective transformations are now supported.
+ 
+ 	* src/Makefile.am (libglitz_la_SOURCES): glitz_programmatic.c,
+ 	glitz_color_range.c goes away and in comes glitz_filter.c.
+ 
+ 	* TODO: Updated TODO list.

--- TODO	9 Aug 2004 22:57:35 -0000	1.10
***************
*** 1,28 ****
! * Remove the solid surface type from the API. 1x1 surfaces should
!   internally work in sort of the same way as solid surfaces do now. So
!   a solid surface type will no longer be needed.
  
! * Remove linear and radial surface types and the color range type. Linear
!   and radial gradients should just be another set of filters.
  
  * Add low-pass sub-pixel filters for HW accelerated color balancing 
!   of per-component alpha masks.
  
  * GL_MESA_pack_invert support.
  
- * Projective transformations.
- 
  * Retained-mode rendering.
  
- * Internal composite interface version 2. This will replace pretty much
-   all of the code in the glitz_composite function. This new interface
-   will be really simple, transformations will be accomplished by just setting
-   texture matrices and repeat will always be handled by HW. However, the
-   GL_ARB_none_power_of_two_texture extension will be required (I don't know
-   any hardware that actually support this yet). This is the perfect solution
-   and definitely the future. (Possible problem with render_texture as we need
-   to be able to set the texture border color and I'm not sure the existing
-   render_texture interfaces allow this.)
- 
  * WGL (Windows GL) backend.
  
--- 1,19 ----
! * Switch to new trapezoid type. Add x_offset and y_offset to
!   glitz_composite_trapezoids, glitz_composite_triangles and similars.
  
! * Add glitz_add_trapezoids, glitz_add_triangles...
! 
! * Fix so that projective transformations actually work.
! 
! * Implement the new convolution and the new gradient filters.
!   (Current filters are broken!)
  
  * Add low-pass sub-pixel filters for HW accelerated color balancing 
!   of per-component alpha masks (possibly with gamma correction).
  
  * GL_MESA_pack_invert support.
  
  * Retained-mode rendering.
  
  * WGL (Windows GL) backend.
