NextGL v1.5

[NickK]

This is a very interesting release. I've added new texture formats and have included support for full palleted textures! This will most accurately emulate PSX graphics at a decent speed. Also, using full paletted textures only consumes a maximum of around 2MB of memory! You should, of course, expriment with different settings to see which work best for your system
New texture page information:

Memory usage guide - Page depth memory usage, etc. -

32-bit -> Uses about 256KB of memory per page. Considered to be truecolor. (Consumes a lot of memory.)

16-bit -> Uses about 128KB of memory per page. Considered to be truecolor. (Use this instead of 32-bit pages if you don't want to use palettized texutres.)

Palettized -> Uses about 65KB of memory per page. Not true color, therefore it's not affected by the following:
1.) Memory management
2.) Sprite limiting (if the sprite's page depth is palettized.)
3.) Memory dumps

Changes in this version:

- Fixed a possible rectangle transparency problem
- Improved the speed of MDECs by using a technique that I used recently in Next3D (A more advanced version of this will appear in later versions of my plugins.)
- Fixed mixing alpha testing and blending together. Should work now for the new blending modes
- Added the 1B - 1F (fake) blending mode
- Added the 0.5B + 0.5F blending mode
- Added the 1B - 1F (real) blending mode (thanks to Pete)
- Added the 1B + 0.25F blending mode
- Added 16-bit color mode as a valid primitive cache page depth
- Added 8-bit (true color) as a valid primitive cache page depth
- Added detection for paletted textures
- Added the paletted texture cache
- Both texture caches are now using version numbers. A bit more interesting that way I think
- Added paletted textures as a valid page depth
- All palletized modes now have dynamic CLUT modification. (Still doesn't work with some specific situations.)
- Fixed the FPS counter. It can now handle up to 4 digits and doesn't leave any sort of misleading numbers behind
- Added hardware brightness (like in Next3D) for much more accurate polygon and sprite brightness.
- The debug output now reports memory in sizes of KB and MB instead of just MB.
- Fixed a display/init bug that prevented some MDECs from displaying properly. FINALLY FIXED!
- Added the "MDEC only" scanlines option requested by Metal Murphy. It's looking good

So the scanlines worked out well afterall hey?!

Glad to see that i've help some one in here... Stay cool
