Filippo Argiolas 5fd66383ab [441/906] sobel: convolve only luma 
Rework Sobel a little bit again making it work as the old one:
1. desaturate input texture
2. calculate horizontal convolution for x gradient and vertical
   convolution for y gradient at the same time (halves the number of
   needed texture lookups)
3. store results in a single texture (red and green channel)
4. calculate remaining convolution (same as above switching vertical and
   horizontal)
5. calculate length of gradient using red and green as x and y
   components.
Optimize wherever possible, store kernels as constants in the shaders,
remove unneeded uniforms. Restore invert property carefully avoiding
using IF.
Still not sure if "full color" convolution will be needed, glfiltersobel
is to be intended as a demo filter and xray, the only effect which uses
sobel only needs edge intensity. Dropping it for now.

BUGS [206/906] Do not use frame buffer object when "input video is RGB" or when "GLSL is not available and YCbCr is available". So frame buffer object is not a plugin requirement anymore. So I decreased the OpengGL version from 1.4 to 1.2 (maybe less?) 2014-03-15 18:36:27 +01:00
