TBD
|

GL_ARB_texture_float extension (not finished yet)
|
||||
|
||||
Supports 16 and 32-bit floating point textures.
|
||||
|
||||
GL_ARB_half_float_pixel extension (not finished yet)
|
||||
|
||||
Adds the GLhalfARB datatype for 16-bit floating point for glDraw/ReadPixels,
|
||||
and glTexImage commands.

||||
Texture image handling
|
||||
----------------------
|
||||
|
||||
The code which implements image conversion, pixel transfer ops, etc
|
||||
for glTexImage commands has been rewritten.
|
||||
|
||||
Now the gl_texture_format struct has a new StoreImage function
|
||||
pointer. Each texture format must implement this function. The
|
||||
function is totally responsible for converting the user's texture
|
||||
image into the specific format. A few helper functions makes this
|
||||
relatively simple.
|
||||
|
||||
Overall, the code is much simpler, cleaner and easier to work with
|
||||
now. Adding new texture formats is straight-forward and there's no
|
||||
longer any distinction between "hardware" and "software" formats.
|
||||
|
||||
Finally, the code for compressed texture images has been reorganized
|
||||
as well.
