This patch fixing:
- A bug introduced in commit
https://github.com/MythTV/mythtv/commit/61453e219 causing bottom and left
screen pixel shimering (green or/and random pixels)
- Adding support for rectangual textures when using openglbicubic resizer.
Optimal will be chage also:[[BR]]
"MAD coord.xy, fragment.texcoord[0], {%6, %7}, {0.5, 0.5};\n"[[BR]]
to[[BR]]
"ADD coord.xy, fragment.texcoord[0], {0.5, 0.5};\n"[[BR]]
when using rectangual texture but diference betwen those two instructions
are negligible.
Changes was tested with Radeon X1300 opensource drivers (gallium and
classsic) with legacy profile, since high profile is not finished yet.
