immDrawPixelsTex - Functions like a limited glDrawPixels, but actually draws the image using textures, which can be tremendously faster on low-end cards, and also avoids problems with the raster position being clipped when offscreen. Pixel unpacking parameters and the glPixelZoom values are not respected.

Attention: Use immDrawPixelsTexSetup before calling this function.; This routine makes many assumptions: the rect data is expected to be in RGBA byte or float format, and the modelview and projection matrices are assumed to define a 1-to-1 mapping to screen space.

Use the currently bound shader.

Use immDrawPixelsTexSetup to bind the shader you want before calling immDrawPixelsTex.

If using a special shader double check it uses the same attributes "pos" "texCoord" and uniform "image".

If color is NULL then use white by default

Be also aware that this function unbinds the shader when it's finished.
