Description

Steps to reproduce the behavior

open the colorscale example in cookbook-expo, select for instead heatmap compare with https://gl-react-cookbook.surge.sh/colorscale . result is totally different..

i'll investigate on a smaller code to reproduce the bug, but basically something is wrong in the texImage2D when sending a typed array.. we need to see if the diff options are supported correctly (gl.ALPHA, gl.LUMINANCE_ALPHA, gl.RGB, gl.RGBA) but it might be something around that

Contributor guide

Research direction
Investigate how texImage2D handles typed arrays for different gl formats (ALPHA, LUMINANCE ALPHA, RGB, RGBA) in the EXGL implementation. Compare the behavior with the expected output from the gl react cookbook example.
