b90d824626 [838/906] gl: Use GL_TEXTURE_2D instead of GL_TEXTURE_RECTANGLE 
We create our textures (in Desktop GL) with GL_TEXTURE_RECTANGLE,
vaapi attempts to bind our texture to GL_TEXTURE_2D which throws a
GL_INVALID_OPERATION error and as thus, no video.

Also, by moving exclusively to GL_TEXTURE_2D and the npot extension
we also remove a difference between the Desktop GL and GLES2 code.

5b9e4b8282 [493/906] glfiltershader: fix crash when loading shader file 
Just use g_file_get_contents() instead of home-made file loading.
Fixes two issues - one is that we should pass "r" to fopen and
not O_RDONLY, the other is that an incorrect variable was used
to read the file length, leading to an empty shader file.

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.

49df4dca3c [440/906] sobel: implement sobel filter using separable kernels 
Reimplement sobel in a multipass fully separated convolution:
- calculate x gradient map convolving first horizontally with blurring
  kernel and then vertically with differentiating kernel
- calculate y gradient map convolving first vertically with blurring
  kernel and then horizonally with differentiating kernel
- calculate length of the gradient vector
Particular care was needed with normalization of the blurring kernel and
with grey level offset of the differentiating one to prevent overflow of
rgb values from the [0.0,1.0] range in intermediate passes.
Now works on i915.

0cae67172a [430/906] convolution: save some indirection grouping math and sampling 
Thanks to Eric Anholt I've finally understood (at least I hope) how to
count texture indirections and save up some.  Texture sampling dependent
on the result of some math counts as an indirection phase. Grouped
texture lookups with no math involved count as a single indirection.
Math on the coordinates count as indirection.
So the best thing is to group all the math involving coordinates and
then do all the lookups.
This saves enough indirections to make glfilterblur and glow effect
work, albeit a bit slowly, on i915.
